for some reason my rear brakes are not working good at all i have bleed them numerous times and they sill dont work right. any sugestions?

 

i would check the wheel cylinder,

when you take off the drum. so you see brake fluild.

if u do the wheel cylinder is bad,

 

every thing is new in the front and rear. no fluid

 

then only thing i can think of, is ur master cylinder is going bad.

 

Have you pulled your hand brake a couple of times? If not you should and report back on your brakes.

 

everything is new. i mean everything. i though that also so i change it again. i have pulled the ebrake a few times and it didnt help, and it does work. the only other thing i can think of is the portion valve

 

i know i posted this a few months ago anyone else have any ideas

 

E-brake doesn't have anything to do with the proportioning valve, it's a solely mechanical device. So if the E-brake doesn't work either, then you have missed getting parts/springs/etc. connected correctly.

 

the ebake does work. that is not the issue. i was just guessing about the portioning valve.

 

My bad - when I read this, I thought you were saying the Ebrake didn't work at all.

What about adjustment of the drums? I'm no good at it at all, but I know once my brother adjusted mine, and it really helped.

Also, are you sure you got the adjustment screw installed correctly? If it's in backwards (I did this once) - then your brakes will try to adjust when braking while moving forwards, instead of adjusting itself when braking by moving backwards? LOL - does that makes sense? Drum brakes self-adjust when braking in reverse - the adjustment piece must be facing correctly in both wheels (which means one side is installed opposite from the other). If it's wrong, it'll adjust itself looser instead of tighter when you brake while driving forward.

 

thanks for the reply but, i am not a rookie when it comes to auto skills. Im not trying to be a jerk but i put everything togeather right, i guess i will need to just spend the money and pay for it to get a power flush and get all the traped air out. that is the only thing that i can think that it is. thanks again for your reply hope i didnt seem to assish. I will have to see what happens after that

 

Hey - no problem. I'm definitely no expert - just passing on ideas that I've had experience with - that's what were all here for - to pass along ideas, some good, some stupid.

 

no problem, i do thanks you, I am sorry if i sounded assish. thanks again sean

 

So the e-brake works but the pedal doen't. Is it weak or are you getting zero movement from the wheel cylinders. Is your pedal firm or soft. How many miles are on the master cylinder.

 

all new parts from front to rear, mushy pedel, if i pull in to my garage and the floor is alittle wet the rear tires will start to spin with my foot pressing hard on the pedel. i i bench bled the master cylinder before install, here are the parts that were changed, front calipers,pads,front brake hoses, master cylinder, rear shoes, wheel cylinders, and rubber line in back. the only thing that i havent changed is the rear drums, all parts only have maybe 100 miles on them have bled the whole system numerous times

 

I had this same problem on a Nova. Where did you get your Master Cylinder from?

We changed every damn brake part on the whole car, even the front hard lines. We could not get a good pedal to save our souls.
It was a bad master cylinder right out of the box.

I assume you've bled the brakes correctly several times. Your not getting any air out of them right? If you done that, the only place air can hide is the MS. Al lot of them are rebuilt (weather they say they are or not) and not all rebuilds are the same.
Try a new one if that isn't it, I'll go find some people smarter than me and ask em.

i had tried that also, i did that about a month ago or so, will wore out drums cause this, the car has 87k on it and the drums have never been changed. my thought. I think i am going to change them and then take it to a place to get it power bleed. thanks for all your guys replies sean

 

I wouldn't think drums would wear out in that few miles. My 1990 have 190k on them, with no problems. The rear brakes see much less force/use, since weight shifts forward - the front brakes get the abuse - hell most people don't even change shoes before they trade cars - 'cause there just isn't the wear on them like the front. But who knows, as usual, anything is possible!

 

I have never heard of worn drums causing a mushy pedal, unless they were extremely worn and the wheel cylinders leak cause they extend too much but then you would see brake fluid, which you didn't see.
