1985-1987 Buick Turbo Regal -
CONVERSION VACUUM BRAKE BOOSTER KIT with New Correct Size PIN for the Stock Brake Pedal
This is another option to consider if you have a fairly stock 1985-1987 Buick Turbo Regal and want to switch from the original powermaster brake system.
This kit comes complete with everything you need as shown. This kit is very similar to Part #7625 however, it does not include a factory vacuum brake pedal. Instead we include a correct size machined pin that needs to be welded to the original stock brake pedal. Directions showing proper measurements comes with it, so this machined pin can be done by a welder on the original brake pedal rod.
It comes with a REBUILT Cardone brake booster and a BRAND new master cylinder. The booster has a 9" diameter. The master cylinder and vacuum booster in this kit are exactly what GM used in 1986-1987 on a non-Turbo Regal application.
There are no clearance issues with this unit and the stock remote power steering reservoir.
It also comes with our new vacuum block with gasket and hardware. It has the vacuum port similar to what GM used on the 1989 Turbo Trans Am. We also include 2 feet of vacuum hose and our new reproduction gasket to firewall.
This booster kit uses the same factory holes in the firewall as the power master.
Since nothing gets cut or drilled related to the original powermaster, the original powermaster can be re-used should you want to convert back to the factory set up at a later date. However, you would need to acquire a brake pedal for a Turbo Regal to have it function properly.
We highly recommend installation be done by a qualified mechanic, since you have to properly bleed the brakes and need to weld the new brake pedal pin to the factory pedal rod. You also have to cut off the original pin from the brake pedal rod. Make sure the system is operating properly under all conditions.
Remember, your best option is always to stay with the factory GM powermaster brake system. This unit is only to be used with a stock or a fairly stock Turbo Regal. A modified engine or one with a performance cam would cause vacuum levels to be greatly reduced, which could cause braking problems. One possible solution would be to purchase an additional vacuum canister to retain proper vacuum levels from Summit or Jegs.
When purchasing this kit, you may also want to purchase Part #7218, Stainless Braided Brake Hoses, as these will improve the stopping ability.
For our rebuilt powermaster brake unit, See our Part #7021 Rebuilt Powermaster Brake Unit.
However, if you have a STOCK engine, there is adequate vacuum to switch over to a vacuum brake system. We have another option: Our Part #7625 - Conversion Vacuum Brake Booster Kit with vacuum brake pedal.
The difference between #7625 and this kit #7679, is that this kit comes with the correct pin instead of a vacuum brake pedal.
NOTE - A vacuum brake system is NOT recommended for a Turbo Regal with a modified engine or one with a performance cam because vacuum levels are greatly reduced, which could cause braking problems.
