I could have gone without that one...

So.. New wheel cylinders all around, new pads all around, new mc(bench bled first), new pushrod, stars all the way out, bleed all the wheels again and the brakes feel mushy. I can pump them and get good pressure but then its gone when I step back down. Maybe I need to bleed again??

Looks like it was ready to be replaced...

Should I be worried about this or can I pretend I didn't see it? I assume/hope its a cheap part? Edit: $8 from TTS but can I install it through the wheel well or do I absolutely have to pull the tank?

You can pretend you didn't see it, and then pretend your steering shaft is still connected to the steering box when it tears the rest of the way! See how that works out for you!!

Replace it ASAP!! And install it the Same way(flanges criss crossed)!!
I'd yank the tank, not that hard to do and will make the job SOO much easier. You probably can get it done through the wheel well though, just more hassle.

Yank the tank. You'll wonder why you didn't when you replaced the master cylinder. Have some spare fuel line around cause you may want to replace that as well. Some people like to relocate their fuel filter under the tank.

Is it possible that brake pressure only in the last 5-10% of the pedal stroke can be from bad rubber lines? I can pump up pressure but then it goes away after I let off the pedal. I dont have a problem replacing the lines but I dont necessarily want to do it and re-bleed for a fourth time just for fun. No problems bleeding as it came out fast and smooth. I just can't think of anything else that could cause it...

I ask because after running a search a couple times I heard that answer and thats the only thing I havent replaced. On the other hand I only have the two short runs of rubber in the front and it seems weird that the lines would be expanding enough to make a differance?!

Semper_Dad · Posted: Mon Feb 13, 2012 4:05 pm Post subject:

If the lines are original then it might be a good idea to replace them anyway. Besides,....after bleeding 4 times, you should be good at it . Laughing

Sorry, couldn't resist Laughing

haha funny man!

I guess I should and its not expensive. Then again this like the millionth time I've said that so I think it is getting expensive Smile

You think it could cause the weak pressure though? I'd rather figure out the problem and fix both issues prior to the fourth bleed... then I can clean up all this hydraulic fluid off my garage floor once and for all.

Semper_Dad · Posted: Mon Feb 13, 2012 6:28 pm Post subject:

Not much really left is there?

You've replaced master and a leaking wheel cylinder. No evidence of leaks anywhere else right?

Not really knowing what condition my "wear parts" are really in, I've tried to start replacing them. Bearings and rubber parts are on the top of the list, especially if safety related. Brake hoses are still on my "todo list". I keep a database of all maintenance and parts replacement that I can go back and review.

Let me know if you'ld like for me to jump to your side of the pond and give you a hand.

is you problem a low brake pedal or brakes not holding it is possible that when you replaced the shoes you turned the adjusters backwards on the shoes and now the shoes are not on the drum correctly you can bleed forever and never get a good pedal if the shoes or on backward

DougD · Posted: Mon Feb 13, 2012 9:37 pm Post subject:

Hmmm that would be easy to fix. If I pull all the wheels and snap some pictures do you think you will be able to tell?

joescoolcustoms · Posted: Tue Feb 14, 2012 7:17 am Post subject:

The rear shoes are hard to put on wrong. The front shoes, maybe.

But, did you adjust the brakes out to the drum when you replaced the shoes? The ACVW design is not self adjusting like many American designs are. So, they require regular adjusting as they wear to keep from needing to pump the peddle to shove the shoe out to the drum.

I never even noticed that angle. Thanks a million for the pictures... never would have thought to check that. I'll take a look tonight.

just trying to help the only way i know these things is i have made almost every mistake you can make you learn by you mistakes

There's 1MM clearance spec from the tip of the pushrod to the bottom of the master cylinder socket that it fits into. That should equate to to 5 to 7 MM of play in the pedal.
