Brake adjustment problem

[schlanks70vdub]

i've got new brake pads, new slave cylinders on all four tires. I've gone around all the wheels and tighted the shoes just until they rub the drums.. now the problem i'm having is, on the left front tire... I screw it down till it slightly rubs the drum then i reach up.. press on the brake pedal, then go back down and spin the wheel again only to find out that the shoes aren't hitting the drum anymore. Is there a bad slave cylinder? or something else that i'm overlooking..

thanks in advance...

new shoes and wheel cylinders (not slave) are only the beginning. There are soft lines that should probably be replaced and then you need to make triple sure that everything is tight.

Bleed, bleed, bleed forever until you are absolutely positive there is no air in the lines. Air is my first guess.

try adjusting it some more now, maybe the shoes were just not centered and now they are.

when i adjust brakes i adjust them out as hard as i can to be sure they are centered then i back them off slightly till i can spind the wheel with slight drag.

After you adjust them drive around the block and do it again, make sure your hoses are good also.
What year bus, do you have the right hardware, did you put the springs on right. Are the shoes seated in the wheel cylinder.

When it rains it pours. I'm having to do abunch of brake work right now on a few VWs, a couple guys on a Thing email thread are having brake problems. I was driving merrily along today and noticed some sponginess developing in the brakes, after a few blocks the brakes were gone, thank the cosmos for e-brake. somehow the left front bleeder had come loose. I hadn't touched my brakes since last summer.

Anyway, I'd agree with previous posts, bad soft line, air , and when adjusting get them as tight as you can and back them off.

good luck, and let us know what you find.

My 67 had a right front wheel that would brake hard then stick like crazy. Turned out to be a collapsed rubber line. It would let the fluid be pumped thru it but it wouldn't let it back out. Works great, i'm gonna change the rears just in case also.

I can now stop with no problem. It was two things.. I tightened the shoes to the drums and backed off till they just grazed the drum. Then I went around and blead the brakes and YEP there was still air in the lines. I will however replace the soft lines ASAP but for now I was driving it around my neighborhood and came to a stop sign. I'm still restoring the bus so all the seats and everything else are just pilled in the back... well, I hit the brakes and the bus STOPPED everything flew forward including me haha so the work great..... BTW someone asked what year... it's a 67... 13window... Thanks again for the help
