I have an 84 Firebird S/E with 4 wheel disc brakes, I am keeping everything stock. I need to replace the master cylinder but I was thinking should I replace the booster and calipers as well they all have the little color dot from the factory on them, they work but they are 28 years old, the master is leaking I think into the booster because there is no fluid leaking out of the car and it is going somewhere, and the brake light is on.

 

From the manual:

"The pressure differential warning switch is designed to constantly compare front and rear brake pressure from the master cylinder and energize the warning light on the dash in the event of a front or rear system failure. The valve and switch are so designed that the switch will latch in the "warning" position once a failure has occurred. The only way the light can be turned off is to repair the failure and apply a pedal force to develop approximately 450 psi line pressure."

Send the master and the calipers out to be restored. Keeping everything stock and original will bring more $$ down he road if you decide to sell.

White Post restorations in VA can sleeve the master and calipers in stainless.

 

The brake parts in these cars are as common as dirt, especially the front calipers. No sense in having those "restored".

A 6-cyl SE isn't a $$$$$$ kind of "classic" anyway; not the right motivation for it. If the owner wants to keep it original, that's his own business; but like many things, it's wise to do things FOR THE RIGHT REASON. Making decisions based on the wrong reasons leads one down paths that end up in the weeds. Big $$$$ at resale time isn't "the right reason" for ANYTHING, on that kind of a relatively low-option kind of car.

But back to the original post... if brake fluid has got into the booster, as seems likely, then yes the booster needs to be replaced. The BF eats the rubber that the diaphragm in the booster is made out of. It will fail, SOON. If the MC leaks in that direction there will be a stain of it on the outside of the booster below the MC. If there's ANY TRACE WHATSOEVER of fluid there, it's toast.

 

Trucker wants to keep everything stock and his calipers have the original factory inspection marks on them. You'll not find these 'common as dirt' brake parts in the auto parts store with those colored markings. THATS the reason I mentioned White Post Resto..and thats what the OWNER OF THE CAR wants.

 

THen he can go to the paint store and buy some colored paint to match.

Didn't sound to me like he wanted to keep that though; what he ACTUALLY said was

which sounds alot more like he means "I can see nobody's touched them since the day they were born which tells me they're probably used up".

Calipers are less than $15 for these cars. http://www.autozone.com/autozone/par...208793_0_2362_ Not worth "restoring".

 

This is a one owner car, so I have to keep the one owner happy. I did a complete upholstery job on it using the original GM palex material in the original colors, as for options it had just about everything you could put in a Firebird in 84, the automatic was an option I believe the stock is a 5 speed stick, yes it has the 2.8 high output v-6 that was the stock engine but the 305 was an option for this car every couple of years we have to replace the rear transmission bolt because the torque from the engine snaps it, this is a touring coupe 4 wheel disc, factory front and rear stabilizers, it even came stock with the smoked trans am taillights plus in 84 there were 128,304 firebirds built out of these only 10,309 were the S/E model. it is a fun little car and I cruise with other f-bodies and the car just looks good it even has a custom paint from Prestige Pontiac that was in Van Nuys the dealer was down the street from the assembly plant and did a lot of the custom paint jobs for the plant.
