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 booster is 9" dual diaphram type.
The 12" single diaphram does not perform as well
as the smaller 9" and 12" 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.
1986 & 1987 Powermaster replacement.
Replace the entire Powermaster with this vacuum brake kit.
The brake pedal must changed which is included.
Booster is freshly rebuilt by Cardone and unpainted.
Booster comes with the one way vacuum fitting on booster.
Master cylinder is new with new good looking brake fluid reservoir.
I have heard the argument that a non Powermaster brake unitwill decrease the value of my Turbo Regal.
I say save the 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 or GN.
This kit is not difficult to install but should have
qualified mechanic install this kit.
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 assistance from the
Powermaster motor is like stepping on a brick. 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 the Powermaster was
not necessary on the turbo car.
