I know of 2 Turbo Regals with rear disc brakes with this kit.The supplied brake pedal puts the booster rod centered out of the rear of the booster body.The Powermaster brake pedal should not be used or the pedal will be low and hard.The New Booster is 9" dual diaphragm type. The 12" single diaphragm does not perform as well as the smaller dual 9”. The 12" booster looks weird mounted under the hood of a Turbo Regal. No need to hunt down accumulators, brake switches or electric motors for the Powermaster. Those days will be gone when you purchase this Powermaster replacement kit.This is a total kit to make the Powermaster go away. Kit for 1986 & 1987 Powermaster replacement. Replace the entire Powermaster with this vacuum brake kit. The brake pedal should changed which is included. No welding or drilling necessary. New Booster comes with the one way vacuum fitting on booster to prevent pressurizing the booster. Master cylinder is new with new good looking brake fluid reservoir.I have heard the argument that a non Powermaster brake unit will decrease the value of my Turbo Regal. I say save Powermaster unit to reinstall if and when you decide to sell your TR. At least you will have brakes with the vacuum setup and not have to worry about blowing the Powermaster fuse and having no brakes and no more T, TType or GN.This kit is not difficult to install but should have qualified mechanic install this kit.Instructions included. Never have to worry about blowing the Powermaster fuse and plowing into a train like my wife almost did. Stepping on the brake pedal at speed with no added pressure from the Powermaster electric motor is like stepping on a brick. It is much worse than a vacuum system when the engine dies at speed.The '89 Turbo TA Firebird with the 3.8 Turbo SFI engine use vacuum brakes from the factory. GM must have figured out the Powermaster was not necessary on the turbo car.Check out my response and you will see all the satisfied ers.
