This Kit is a Bolt In. No Cutting. No Drilling.
One modification is necessary. Tee into vacuum
line for booster vacuum. Tee and vacuum line included.
This is detailed in the instructions.
Master cylinder bore size is the same size as the Powermaster.
No need to change proportioning valve.
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 diaphragm type.
The 12" single diaphragm does not perform as well
as the smaller dual 9”. 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 should changed which is included.
Booster comes with the one way vacuum fitting.
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 a 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, TType 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
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
uses vacuum brakes from the factory.
GM must have figured out the Powermaster was
not necessary on the turbo car.
