Question:

will all the air come out of a brake system even if a caliper is bad?

i have a 91 honda crx.i bled the brakes on it and i had no trouble with two wheels.the other two wheels when i crack the bleeder it hardly leaks any fluid if any at all.ive bled them numerous times and still same thing.the ones that wont bleed had pads that were still good.one front wheel and one rear on opposite sides wont bleed.help.please dont say bring to a professional.

Answer:

i heard you the first time
They have it at my local Agway.
bad distribution valve/you do need a pro/thoise good pads were the ones that were not working/brakes is no place to start your mechanics introduction/can get bad case of splat
Do you have disc or drums in the rear? First of all pull the bleeder screws out of the 2 that won't bleed and blow through them to make sure their not clogged with rust, dirt etc.clean if clogged if not next check to see if the wheel cylinder (If drums in the rear) is leaking. Pull back the rubber boot to see if fluid seeps out. Next try disconnecting the connection before the rubber brake hoses at each wheel and have someone press the brake pedal and if your getting a good flow then your brake hoses are breaking done internally (collapsed) and restricting the fluid pressure. If your pads are wearing unevenly check the slides to make sure they're free. If all of this doesn't work and you don't have access to a pressure bleeder, I'd say the two that don't bleed (calipers) need to be replaced. Usually this occurs because of neglecting to flush your brake fluid( brake fluid is hygroscopic and over time will absorb water, that's why old fluid will have a greenish, brownish tint, from moss/algae. Also snow(salt) and age will rust the piston inside the bore causing it to stick. Good luck and hope this helps.
