Strange rear brake problem, (FIXED)

I just replaced my rear axle seals and when I re-installed my brake lines and bleed them I can't get a hard pedal. The shaft on the drum that the parking brake cable hooks to (with the spring attached to it) also moves back and forth on the driver side when the pedal is pushed. (I don't think it is suppose to) I have no idea what the problem is. Help me guys, I need to get it set for the Melt.

Re: Strange rear brake problem, help

We had the same kind of problem when we changed the rear drums...but you have to crack the drum open and look at it??

That arm that the cable attaches is the adjuster/e-brake
arm. take it out and make sure that all the parts on it move freely. The arm that sticks through the backing plate should move freely, They usally rust solid.also there should be a
spring on the adjuster part (Little pawl on the arm.)
It sounds like the brakes are not adjusting up properly.

Re: Strange rear brake problem, help

You're right, the parking brake cable spring shouldn't move with the pedal - something is ascrew. I'd pull the drum off again and check the setup, see that nothing is binding or misaligned. Sounds like some part is pulling or rubbing inside the drum. Also, it takes a while to get a good bleed on those lines. I thought I had all the air out of mine, but the pedal was still a bit mushy, drove it for a few days, then bled them again and got lots more air out. Now they are ok. Hope you have the same luck.
See ya at the Melt!

Re: Strange rear brake problem, help

Thanks for the replies, i just put all new pads on today and while driving down dirt roads i can't even get the tires to lock up, not even the front. I have no idea how they could have gotten messed up. Scott how many times did u have bleed your brakes? I've done each corner about 15 times now.

Re: Strange rear brake problem, help

Before you go through gallons of brake fluid like I did, try to gravity bleed them. Attach a hose and a receptical to each bleeder and open them up. Allow it to flow into the recepticles and keep an eye on the master cylinder fluid level. It could take more than an hour or so to do but this helped me out when I had bleeding problems.
Another trick used on the rear is to jack up the entire rear end, and put a "c" clamp on the brake cylinders compressing them. I was told of an air pocket inside the brake cylinder can make bleeding a PITA. Hope this helps....

Re: Strange rear brake problem, help

Ohh, 15 times?! Not that much for me. I did it about 5 or 6 times, then after driving around a bit, to shake things up, I did it another 4 or 5 times. On the 88.5 and up models, there is only one line to bleed for the rear end. /wwwthreads_images/icons/smile.gif less work.
