Heavy Duty Dual Diaphragm Brake Booster and 1" Bore Master Cylinder. Replace rusty, leaky and faulty Brake Booster & Master Cylinders with a HD kit from RT Off-Road. Two performance level kits were designed to specifically cater to the vehicles requirements. The larger bore Master Cylinders are designed for upgrades done to axles with larger brake calipers. The more moderate bore is designed for vehicles with factory brakes, disc brake upgrades and vehicles that require more braking power. Each kit consists of a zinc-coated Brake Booster, Master Cylinder, bench bleeding kit and installation instructions. Installation involves replacing the factory brake booster and master cylinder.

Q: I am running a Howell TBI system with an 8" open air cleaner on a 4.2L engine.. Will I have enough clearance for this upgrade? Answer this question
A: The vendor is not sure on this one, they haven't tested that combination of parts.

Q: The instructions state that the brake pedal height will be higher than original. How much higher than original? Also, how much reduction in required brake pedal pressure does this upgrade provide compared to stock? Answer this question
A: Pedal height varies from Jeep to Jeep. I haven't heard of any issues though. Pressure Required: Again, it varies depending on what brake setup you have/had, the age of the components, etc. It's a fairly considerable increase in booster assist though.
