Best Drum To Disc Brake Conversion Kit for Cars and Mini Bikes

#1 · Best Overall

1. GPS Automotive LEED FC0001-405

• Weight: 60 lb
• Compatible with Vehicle Type: Car

Best for: Bolt-on manual front conversion.

Why it ranks #1: A direct bolt-on manual conversion mounts factory-style four-piston discs to original drum spindles, with a cast-iron master cylinder and adjustable proportioning valve.

A direct bolt-on layout mounts factory-style four-piston disc brakes to original drum-brake spindles without cutting, drilling or welding. This LEED Brakes manual conversion also includes a cast-iron master cylinder and adjustable proportioning valve, giving builders key control components in the specified package.

Using the original drum-brake spindles as the mounting point can avoid spindle replacement, and the listing describes installation as direct bolt-on with no cutting, drilling or welding. The factory-style four-piston brakes supply a specific caliper configuration; the cast-iron master cylinder and adjustable proportioning valve are named components that let the manual system be configured as part of the conversion. The supplied facts do not identify vehicle fitment, so the listing alone cannot establish application compatibility.

Skip it if you need an explicitly named vehicle application; GELUOXI 433126A lists Ford 8- and 9-inch small-bearing rear fitment.

This suits a builder seeking a manual, factory-style four-piston conversion with a bolt-on spindle approach and named hydraulic controls. The supplied product facts do not state vehicle fitment, so they do not establish whether it applies to a particular car.

#2 · Best Ford Axle Fit

2. GELUOXI Ford 8/9-Inch Kit

• Compatible with Vehicle Type: Car

Best for: Ford small-bearing axle conversion.

Why it ranks #2: Specifically replaces Ford 8- and 9-inch small-bearing rear setups, includes parking-brake cables, and avoids welding or fabrication; it requires 14-inch discs or larger rims.

No welding or fabrication is required for this GELUOXI rear conversion for Ford 8- and 9-inch small-bearing applications. The kit includes mounting hardware and three kinds of shims, giving installers adjustment options while making wheel clearance and axle removal important parts of the job.

The stated Ford 8- and 9-inch small-bearing application narrows the target, while the three kinds of shims let the installer adjust brake spacing according to the rear axle. Three different flanges are also specified for selection according to axle flange details. Although the listing says no welding or fabrication is needed, the axles must be removed. Wheel requirements are explicit: 14-inch disc-brake wheels or 15-inch-or-larger rims are required.

Skip it if you need to keep the axles in place; Speedmaster PCE164.1014 is a GM rear conversion, not a Ford small-bearing kit.

This is for Ford 8- or 9-inch small-bearing axle owners who can remove the axles and meet the stated wheel-size requirement. Its shim and flange choices aid axle-specific setup, but the listing does not make this a no-disassembly installation.

#3 · Best G-Body Coverage

3. Fizzvex G-Body Rear Kit

• Weight: 50.9 lb

Best for: G-body and S10 rear conversion.

Why it ranks #3: Lists several Buick, Chevy, Oldsmobile, and Pontiac applications and includes drilled-slotted 11-inch rotors, calipers, emergency-brake cables, hoses, and hardware.

Two drilled-and-slotted 11-inch rotors and calipers with built-in emergency brakes define this Fizzvex rear conversion. The listed applications cover several G-body-era models, while two bolt patterns and included emergency-brake cables give buyers specific wheel and parking-brake details to consider.

The package lists two 11-inch drilled-and-slotted rotors, calipers with built-in emergency brakes, two emergency-brake cables, rubber hoses and mounting hardware. Having the cables and hoses specified alongside the brake components helps buyers account for more of the conversion system. The stated 5-on-4.5-inch and 4.75-inch bolt patterns give concrete wheel-pattern information. Listed vehicles include Buick Skylark, Chevy Camaro, El Camino, Malibu and Monte Carlo, plus Oldsmobile and Pontiac applications.

Skip it if you need a conversion specifically listed for a 1963–1970 Chevy C10; D-ETEGNIK DY-301-008 names that truck application.

This suits owners of the listed Buick, Chevy, Oldsmobile or Pontiac applications who need a rear conversion with emergency-brake parts included. Its rotor and bolt-pattern specifications are useful selection details, but its vehicle list defines the stated application.

#4 · Best C10 Match

4. D-ETEGNIK C10 Rear Kit

• Compatible with Vehicle Type: Car

Best for: Six-lug classic C10 conversion.

Why it ranks #4: Targets 1963–1970 Chevy C10 trucks with six-lug wheels and lists rotors, calipers, brackets, hoses, and hardware for a complete rear conversion.

Specific fitment for 1963–1970 Chevy C10 trucks and six-lug wheel compatibility make this D-ETEGNIK rear conversion a focused classic-truck option. The listed package includes rotors, calipers, brackets, hoses and hardware, covering the named parts of the drum-to-disc conversion.

The application list covers 1963–1970 Chevy C10 and GMC15 trucks, and also names 1963–1970 Chevy Suburban and 2WD Blazer models. Six-lug wheel compatibility is specified, helping define the intended wheel setup. Rotors, calipers, brackets, brake hoses and necessary hardware are included according to the listing, so buyers can account for these major conversion components in one kit. The supplied facts do not state an installation method or rotor dimensions.

Skip it if you need a Ford 8- or 9-inch small-bearing rear kit; GELUOXI 433126A names those Ford applications.

This fits classic-truck owners whose C10, GMC15, Suburban or 2WD Blazer appears in the stated years and who use the listed six-lug setup. The major brake components are specified, but installation details and rotor dimensions are not.

#5

5. Mixizap Ford 9-Inch Kit

• Compatible with Vehicle Type: Truck

Best for: Ford 9-inch axle conversion.

Why it ranks #5: A bolt-on rear kit for Ford 9-inch axles, with specified axle-offset and flange-diameter limits; it suits buyers who can verify those measurements.

Axle-offset and flange-diameter specifications make this Mixizap kit a clearly dimensioned option for Ford 9-inch rear ends. The listing also describes a serviceable disc-brake design, giving owners concrete fit boundaries to check before choosing a rear drum-to-disc conversion.

The kit is specified for Ford 9-inch axles with minimum axle offsets from 2-3/8 to 2-1/2 inches and a maximum flange diameter of 6-1/4 inches. Those measurements provide practical screening points for axle compatibility before installation. Mixizap describes the design as serviceable and says it is intended to improve stopping power over traditional drum brakes. The supplied details identify a rear-end conversion kit, but do not provide an installation method or component-by-component inventory.

Skip it if you need a listed Ford 8-inch application; GELUOXI 433126A explicitly covers Ford 8- and 9-inch small-bearing brakes.

This is for Ford 9-inch rear-end owners who can compare their axle offset and flange diameter with the listed limits. Its serviceable design is a stated benefit, but the supplied details leave installation method and included components unspecified.

#6

6. Speedmaster PCE164.1014

• Weight: 79.2 lb

Best for: Track-use GM rear conversion.

Why it ranks #6: Offers a rear kit for GM 10- and 12-bolt applications with vented slotted rotors and mechanical parking-brake provision, but is designated racing-only, not street use.

A mechanical parking-brake provision distinguishes this Speedmaster rear conversion for GM 10- and 12-bolt applications. It pairs that provision with a vented, slotted rear rotor and included brake lines, giving racing-focused buyers a conversion with several named braking components in the package.

The listing identifies a vented, slotted rear rotor and steel caliper with a single piston, providing concrete details for buyers planning a rear-disc setup. Brake lines are included, which means they are part of the supplied conversion, while the master cylinder is not included and must be considered separately in the build. A mechanical parking-brake provision is specified. The legal notice limits this kit to racing applications and explicitly says it is not for street use.

Skip it if you need a street-use conversion; GELUOXI 433126A is listed for Ford 8- and 9-inch axles instead.

This is for a racing-applications-only build using a compatible GM 10- or 12-bolt rear end. Its mechanical parking-brake provision and included lines are useful package details, but the master cylinder is not included and it is not for street use.

#7 · Best Mini-Bike Coverage

7. Feralmoto Mini Bike Kit

Best for: Broad-fit weld-on mini-bike upgrade.

Why it ranks #7: Lists Coleman CT200U, BT200X, Axis M200, Baja, and other mini-bike fitments, with a 63mm caliper and 160mm rotor; adapter installation requires welding.

A weld-on adapter paired with bolt-on components gives the Feralmoto mini-bike conversion a two-stage installation approach. Its listed fitment ranges across Coleman, Axis and several Baja models, while the stated 63mm caliper and 160mm rotor identify the principal brake dimensions.

The compatibility list names Coleman CT200U, BT200X and CT200U-EX, along with Axis M200 and multiple Baja mini bikes. That range gives owners several platforms to check against the listing. The kit converts drum braking to disc braking using a weld-on adapter plate and bolt-on components, and it does not require a tire change. The specified 63mm caliper and 160mm rotor add useful sizing details, but welding remains part of the installation workflow.

Skip it if you require an installation without welding; GPS Automotive FC0001-405 is described as a direct bolt-on conversion without welding.

This suits owners of listed Coleman, Axis or Baja mini bikes who want to retain their tire and can arrange adapter welding. The bolt-on components simplify part of the process, but the weld-on plate remains a necessary installation step.

Listed on Amazon as: Drum to Disc Brake Conversion Kit for Coleman CT200U BT200X CT200U-EX Axis M200 Baja MB200 Mini Bike, 63mm Caliper 160mm Rotor – Weld-On + Bolt-On Upgrade, No Tire Change Needed

#8

8. RZEOZU Mini Bike Kit

• Compatible with Vehicle Type: mini bike

Best for: Weld-on Coleman mini-bike fit.

Why it ranks #8: Fits several Coleman CT200U and BT200X variants and other 200cc mini bikes, but requires welding and professional installation guidance.

Compatibility with the CT200U-EXR and several other Coleman mini-bike variants is the defining feature of this RZEOZU hydraulic conversion kit. It changes a drum-brake mini bike to a hydraulic disc setup, while its installation notes make welding and surface preparation central to the project.

The listed fitment spans Coleman CT200U, BT200X, CT200U-EX, CT200U-EXR and selected BT200X variants, as well as 196cc Hisun and Pum 200 mini bikes. That broad named coverage can help owners identify an applicable platform, while the explicit Baja DB30 exclusion rules one model out. Installation requires welding; the instructions call for polishing and removing paint before welding and recommend professional guidance, so this is not a simple bolt-on conversion.

Skip it if you need to avoid welding; GPS Automotive FC0001-405 is described as a direct bolt-on kit without welding.

This fits mini-bike owners whose model appears in the listed Coleman, Hisun or Pum applications and who can handle a welded installation. Check the stated model coverage carefully: the Baja DB30 is specifically excluded.

#9

9. JMCHstore Mini Bike Kit

• Weight: 2.29 lb

Best for: Weld-on mini-bike wheel conversion.

Why it ranks #9: Converts a compatible mini-bike drum wheel without replacing the wheel or removing the tire, but requires welding and excludes the Baja DB30.

Welding the adapter plate directly to the original drum hub lets this JMCHstore kit convert a mini bike to disc braking without replacing its wheel or tire. Its listed fitment covers several 200-class models, making the existing wheel the center of the conversion rather than a replacement part.

The weld-on plate attaches to the original drum hub, and the kit is specified to convert the existing wheel without tire removal. That can simplify the wheel-side workflow, but welding is required and professional welding is strongly recommended. Listed models include Coleman CT200U, BT200X, Massimo MB200, AXIS M200 and PUMA 200; the supplied facts also identify CT200U-EX compatibility. The listing explicitly excludes the Baja DB30, so that model is outside the stated fitment.

Skip it if you need a no-weld installation; Feralmoto FM-DBTSB also uses a weld-on adapter plate, so it is not a no-weld alternative.

This suits mini-bike owners keeping their existing wheel and tire while converting the hub to disc braking. Choose it only if the listed model fitment applies and you can arrange the required welding; it does not fit the Baja DB30.

#10

10. Mzmotpv 110mm Brake Ring

• Weight: 2 lb

Best for: Compact motorcycle ring conversion.

Why it ranks #10: This is a universal 110mm-to-70mm tightening ring for a 220mm disc setup, not a complete conversion kit with listed calipers, hoses, and mounting hardware.

A 110mm drum ring with 70mm hole spacing is the central specification of this Mzmotpv conversion part. It is intended to adapt a rear drum-brake mounting arrangement for a 220mm disc on a motorcycle, electric scooter, e-bike or moped, with an alloy ring supplied.

The ring is specified at 110mm in diameter with 70mm hole spacing, giving buyers two concrete dimensions for assessing the conversion interface. The listing describes it for a 220mm disc and identifies universal motorcycle make coverage, as well as electric scooters, e-bikes and mopeds in the title. Installation guidance calls for removing the existing drum components, fitting the tensioning device and tightening connections securely. The package contains one motorcycle brake disc kit ring.

Skip it if you need rotors, calipers and hoses in one kit; D-ETEGNIK DY-301-008 lists those components for classic trucks.

This suits a two-wheel vehicle owner seeking the specified 110mm-to-70mm ring arrangement for a 220mm disc. The supplied item is one alloy ring, so buyers needing a complete brake system should account for the limited package contents.
