brakes, again.

[Lugnut]

Hello the board. You know I read a lot of questions, comments on brake problems here. I have had a lot of trouble with mine, like brakes locking up. etc. I corrected that problem by changing the brake hoses. I also put a rebuild kit in the master cylinder. We tryed and tryed to pump up the brakes, to no avail. Found out the new piston was stuck in the cylinder about half way. Since the old parts looked almost new I re-installed them. Now I have free travel of the piston, and I hope I asjusted the linkage correctly. But I am waiting for my buddy to come over and help me bleed the brakes system again. At this point I have no firmness on the pedel at all. I am thinking about bleeding my aircompressor down to abour 20 LBS and blowing air thru the lines with one bleed valve open. What do you think??

NEGATIVE!!!!.....Don't do it.

Either do it with 2 people....or use the bug sprayer pressure set-up or the vaccum pump at the bleed nipple.

Bill.

Could you tell me more on that, sounds very interesting.

Many thanks.

The technique here is to pressurise the brake system using a pump-up garden-sprayer. It acts as a resevoir of fluid and saves all that filling in small doses.

You will have to make up an adaptor to fit the sprayer to the M/C cap.

Bleeding then becomes a one man operation.

Lugnut, we have found it easier in the garage to use the vacuum pump. You don't need any adapters for different vehicles. You just fit the rubber hose over the bleeder and pump the lever and the fluid runs into the little resevoir along with any air. It's a simple one man job and the little pumps are fairly cheap. It has other uses as well so it's handy to have anyway. I have a buddy who uses his every spring to bleed his system. He likes to get all that moisture contaminated fluid out of the system and new stuff installed. He says his wheel cylinders will never pit from moisture. He makes a good point but I have never followed his lead on that one. Cheers,
Barry

First make sure all your shoes are properly adjusted to much travel by the wheel cyl. will give you dead pedal in that the master can't move enough fluid to take up the slack. Napa has a pressure-ball brake bleeder for about $300.00 sure its steep but with mutiple vehicles and changing fluid semi annually it may be worth it ?
Hope this helps
