Brake booster

[secretagent]

I just completed a rear disc conversion, I also replaced the master cyl and the booster. The problem I have is the brakes drag after a while, so muchthat I can feel it pulling, even under acceleration. I didn't know what to do so I pulled the vacum hose and check valve from the booster and it released the brakes, what does that mean, is the booster bad or do I need a new check valve. Please help.

It sounds like everything (check valve and booster) are fine and that you need to do some adjusting on the booster rod to be sure it is fully releasing when your foot is off the pedal.

Depending on which MC your running, this http://www.ih8mud.com/tech/residvalve.php could be the fix for you.

Yeah - the free play is getting messed up. the booster linkage needs to be adjusted, sorry i don't know wchich way to go to fix it. I would assume that you need to lengthen the rod a little.

Where did you get your booster? I'm still having problems finding a reasonable source for my '76, thinking about just trying the older style.

Haystaks, First the rod should be shortened if it's not releasing, and second, a neat replacement booster/master is a complete unit from a 95 Tacoma, with a 1/2" spacer between the booster, and the firewall. Bought one at a re-cycler for $75.00, a lot better than oem, and the brakes are much better than new! HTH, Earl
