brake issue

[psfr311]

recently i have noticed that my pedal is more spongy than it usually is.

I also noticed that if i push the pedal in enough for the brake lights to come on i hear a noise that sounds like air being blown out coming from the master cylinder area.. cant figure out what it is


any suggestions

hows the fluid level? do you have a leak? Sounds like you have air in the system.

 

[psfr311]

fluid level is good.

no leaks at all that i have found

i was thinking air also i am going to re bleed my front calipers today and see if that helps

 

[sumo]

yes try bleeding see if that helps

 

[psfr311]

just rebleed the brakes.. no air bubbles came out


still the same softness on the pedal

i do need to adjust my rear drums but didnt think that would be causing the problem.

so ive noticed that in stop in go traffic/ or if i let off the brake again and reapply within 2 seconds that the brake pedal is extremely HARD to push and the engine tries to bog down if idling for a second or two then it all corrects itself


any suggestions?

brake light switch?

Having your rear drum setup adjusted is important. But now it sounds like something is wrong internally with the booster.

i recentl adjusted the rear drums.

but this started happening before i even touched them

take it in and half a shop diagnose it?

or should i just replace the booster

For the cost of diagnosis and maybe booster replacement by a shop, you can do booster and master cylinder and maybe a few other brake parts yourself. also check you vacuum hose for breaks too.

if i was considering hydro boosting what else what i need to replace?
