Trailer Air to Hydraulic Drum Brake Conversion Kit
The Trailer Air to Hydraulic Drum Brake Conversion Kit is designed for trailers using Dexter or Lippert hydraulic drum brakes and trucks equipped with air brakes. It features a 1,000 psi rating, enabling reliable conversion from air to hydraulic drum systems. This kit targets trailers with established drum brake setups seeking improved control and responsiveness without a full system overhaul.
Key considerations: suitability for Dexter or Lippert drums, compatibility with air-brake-equipped trucks, and the 1,000 psi specification which informs performance and valve sizing. Installation depth depends on axle end configurations and drum dimensions.
Speedway Motors Bolt-On Rear Disc Brake Conversion Kit
Designed for GM 10- and 12-bolt rear ends in mid-size cars, this kit upgrades from drum to disc braking with a bolt-on installation. It includes two bolt-on caliper brackets, two vented rotors, two GM metric calipers, and necessary hardware. The kit emphasizes a budget-friendly path to improved stopping power and simpler maintenance, though it is not intended for full-size cars or 7.5″ 10-bolt axles.
Considerations include ensuring correct rotor and caliper compatibility with your axle, and confirming wheel clearance and stud length for safe disc brake operation.
TeraFlex 4354425 TJ Rear Disc Brake Conversion Kit
The TeraFlex TJ rear disc brake kit focuses on Jeep TJ models, offering a conversion to disc brakes with included components and hoses. Important notes warn that ABS sensor installation isn’t supported in this kit and that some factory wheels or aftermarket wheels may require longer wheel studs for proper clearance. Wheel fit and caliper clearance are essential checks prior to installation.
When evaluating this kit, consider wheel compatibility, potential caliper interference with existing wheels, and the need for longer studs if using aftermarket wheels.
Speedway Motors Complete Rear-End Bolt-On Disc Brake Kit
This universal kit is designed for Ford 8- and 9-inch rear ends, offering a full disc brake upgrade that includes two bolt-on caliper brackets, two vented rotors, two GM metric calipers, brake pads, and the necessary hardware. It’s intended to boost stopping power with a straightforward installation, though fitment varies by axle style and hub configuration. It’s well-suited for users seeking a complete, ready-to-install disc brake conversion.
Brake Bracket Adapter 2pcs (160/22mm & 160/31.8mm)
The Brake Bracket Adapter set is designed to help convert bikes to disc brakes and can assist with mounting compatibility in non-standard configurations. While not a direct trailer ABS conversion kit, these adapters may facilitate disc brake conversions on non-traditional frames or components, expanding mounting options for refurbished or custom builds.
Buying Guide: Key Purchase Considerations
- Compatibility: Verify axle type, drum vs. disc, and whether the kit supports your vehicle’s or trailer’s wheel size, hub style, and rotor diameter.
- ABS integration: Some kits do not include ABS sensors or wiring; confirm sensor compatibility if ABS was a requirement for your system.
- Installation complexity: Some kits are bolt-on and straightforward, while others require fabrication, longer wheel studs, or precision alignment to avoid caliper interference or rotor rub.
- Brake performance: Look for rotor venting, caliper type, and pad materials that suit your load, terrain, and stopping power needs.
- Wheel clearance and studs: Aftermarket wheels may need longer studs or spacers; check clearance between calipers and wheel, as well as brake line routing.
- Maintenance and parts availability: Consider the availability of replacement rotors, calipers, and hardware for ongoing upkeep and safety.
- Warranty and support: Confirm the manufacturer’s warranty coverage and support options for installation guidance and compatibility questions.
Across these options, the best choice depends on your specific vehicle or trailer, the desired braking performance, and how much you value a fully integrated, ready-to-install solution versus a more customizable approach. Always verify fitment with your axle model, wheel choice, and any ABS or electronic components you plan to integrate.
