Mk1 Brake Booster Delete eliminates the Mk1 car's bulky factory unit and improves feel at the traction threshold. A cleaner and more spacious engine bay results in the process.
Note: Required oedal effort increase noticeably vs with power-assist. This may not be suitable for all drivers. For optimal braking performance and safety, USRT recommends pairing this kit with our VW Mk1 280mm Big Brake Caliper Spacers together with 280mm rotors.
The package includes a stainless steel actuator pin which must be installed into the clevis joint on the brake pedal. When setting up the linkage, the measurement from the centre of the clevis holes to the end of the actuator rod should be approximately 128 mm.
After installation, ensure there is slight free play between the actuator pin and the brake master cylinder. The linkage must not be preloaded or solid, as the master cylinder piston must always be able to return fully and move freely backwards. Failure to maintain proper free play may result in brake drag or improper brake operation.
These kits are designed to work with VW Mk2 and Mk3 brake master cylinders (357611019B) with a 22mm or 22.2mm bore diameter. Manufactured from durable mild steel and finished in a black powder-coated finish for excellent corrosion resistance, this piece will live a long service life.
