I am assuming you are referring to a spring brake assembly on air equipped vehicles. If this is the case, normally a leaking chamber would not cause an air compressor to go bad. Some causes for air compressors not to build pressure are: defective air governor, restricted air intake and discharge hose (hose from compressor to air dryer or air tank), bad check valve at dryer or tank, leaking discharge hose (mainly the cloth covered-Aeroquip-spray soapy water at hose with engine running, if it bubbles hose is leaking thru the cover), unloader valve at compressor and some other. The ones I mentiond here are probably the most common.
brake booster could be bad the seal around the rod that hooks to the brake pedal is leaking
Master cylinder is bad and appears to be coming from the booster.
The power brake booster is leaking vacuum.
Probably have a defective power brake booster or the vacuum supply to the booster is restricted or leaking.
No, the brake booster operates off of vacuum not electricity. If the booster isn't working then check the vacuum line going from the intake manifold to the booster. If the line is ok and not leaking then you need to replace the booster.
chances are its a leaking brake booster or rear seal on master cyl.
The power brake booster is leaking vaccume.
The power brake booster is leaking vacuum and that makes the engine die when the brakes are applied. Replace brake booster.
It could be a leaking vacuum hose to the power brake booster or the membrane in the booster could have a hole. When the brakes are applied, the booster is opened to the engine vacuum via the hose. The vacuum leak would then increase, causing the engine to stall.
The brake booster is leaking vacuum pressure. If you look under the hood its black and round and located behind the brake fluid reservoir
it could be a lot of different factors such as master cylinder is leaking past seels, crack in a brake line, leaking wheels cyclinders or calipers, air in the brake system that will cause brake pedal to go to floor if it is hard and wont move could be a failed brake booster
Sounds like it could be a vacuum leak at the power brake booster Check the lines to booster and the check valve at the booster Could be a defective brake booster also
