When I changed the brake fluid, I pumped and bled the brake fluid until all new brake fluid squirted out the bleeders, so it has been completely changed. The brakes worked fine for about 2 months after that until the rear brake pedal started acting up by having to pump it to hold a pedal.

i bled the system according to the service manual instructions at least twice after that, with no results. I just feel like as many times as I have bled the system, all air would be out.

Does this change your thoughts any or should I just keep bleeding it?

 

If it is not leaking and it works when you pump it, it must still have air in it some where.

You could try to remove the rear caliper and use a "C" clamp to push the piston in and there by push any air out of the caliper and into the line.

I have had some trouble bleeding the fronts at times.

I really think that there is still air in the system.

 

Thank you TimBucTwo! I will give it another try this weekend. It sure has been aggrevating!!!

 

I know this may sound a bit strange, but are you perhaps running old brake hoses that are swelling ? It's not a likely one, but you've had such a struggle I had to ask.......
Brake fluid was all new, clean and clear ?
If so, air in the system seems to be the only logical answer.

I'd have gone nuts by now, Ronnie !

 

Here are the steps to follow, you can print them out. You only have to do the rear brake part.
I had red fluid in mine and then bled them with some clear fluid. That way I knew for a fact that the entire line was purged of air when I saw the clear stuff come out.


Steps are as follows;

loosen the orifice bolt by backing it out against the snap ring and then stop.

using the lever:
bleed the right front caliper from theupper bleed valve.
bleed the left front caliper from theupper bleed valve.

using the pedal:
bleed the front right caliper from the lower valve.
bleed the front left caliper from the lower valve.
bleed the rear caliper from the lower bleed valve
bleed the rear caliper form the upper bleed valve.

Tighten the orifice bolt. Do not over tighten it.

Note: You need to keep adding fluid to the reservoir or it will run dry. If this happens you start all over.

 

Heres an Update!!

I bled the brakes again this weekend using the service sequence as I have done before.I DID NOT use the vacuum, but used conventional bleeding.I noticed before I had not been opening the rear bleeders vavlves very well due to the muffler blocking the way of my wrench. This time i moved the wrench and opened the rear bleeders more so the fluid could really push out. Now I have better rear brakes. The first push of the rear brake will give me a pedal, just not a full pedal. The second pedal really gives it stopping power. I may need to bleed one more time.

So, TimBucTwo, I think you were on to something!! There must have been air in the lines. Not sure how it got in there, because the brakes worked fine after I initially changed all the brake fluid. Im thinking a bleeder valve may have not been tightened back good and allowed air to get back in the system.

By getting a rear brake pedal, my front lever brake is now giving me rear brakes through the linked braking as well. Before it wouldnt. I have tested it before and after.

TimBucTwo, you mentioned not over tightening the orifice bolt. I tighten it fully, but dont know how much torque I use. Just hand tight. Is that ok?

 

I would just snug it up like you do with the bleeder.

It's great to hear the good news.

 

Here's an update on my braking problems. I hope someone can offer me some more suggestions:

If i squeeze the front brake first, i have a full pedal on the rear brake. If I just push the rear brake without using the fron brake lever, the pedalgoes all the way down and has to be pumped to get a full pedal of brake.

I have bled the brakes about 5 or 6 times, and I dont think its possible it has air in the lines.

Any suggestions are welcome.

 

I wanted to update everyone on the outcome of my brakes. The rear master cylinder was bad. It actually caused the rear caliper to lock up a couple of times.

We put a kit in it and bled it according to the manual and it works like a charm. For some reason though, the bleeding had to be done using the vacuum bleeder and manual bleeding. Manual bleeding alone just wont work.

 

FINALLY !!!
Good one Ronnie and TBT
