And none better than a snap of his maiden voyage!

The Elky came out great! Don't understand the brake problem at all.... Are both pads hanging up, or possibly just the inner or just the outer??? Maybe the caliper isn't centered on the rotor or something weird like that?? I've never heard of a proportioning valve holding back pressure, don't really see how it could be the culprit.... Possible the wrong master cylinder was in the wrong box???

Thanks Dave. The caliper brackets may be off slightly, but after the pads get wore down after four weeks of driving, I would think they would eventually stop dragging. They aren't. Still dragging slightly. Oh and both inner and outer are wearing the same amount. Just put new pads on and they are now half gone inner and outer on both sides, rear only. Puzzles me.

David,
Not saying it's your problem, but my front calipers were hanging up where the caliper slides through the caliper bracket. I had to do a little bit of creative grinding with a flap wheel on an angle grinder, relieving the bracket just a tad. This can be a bigger issue if you paint the calipers & bracket disassembled, using hard epoxy primer and then a thick finish coat of paint. I hope it's something that simple.

Wish it were that simple too Roger. Left them unpainted. And my calipers slide on the caliper bolt. The bolt threads into the bracket and stays put, and then the caliper floats on the bolt.

If the pads are wearing out that fast, something must be holding a lot of pressure on the calipers...as long as the calipers themselves aren't hanging up...What calipers are on the rear?

Dave, we were using Cadillac Seville with ebrake but had to much trouble with them leaking around ebrake screw so we changed over to the D154 S10/Monte Carlo style calipers.

David

Hmm. Used the same caliper a bunch of times with no problems. All the slider parts on the caliper work good, I'm sure? I guess I'd be for screwing a gauge into the rear brake line fitting at the master cylinder, then after the proportioning valve to see which is holding the pressure.....

Yes. I'm going to try that tomorrow Dave. I did buy a gauge kit as you suggested a while back. The pressure should peak when pedal is pushed in, shouldn't it all but disappear when pedal is released since its a disc brake? I was told that disc brakes have no residual pressure valve like drums do. I just have to get the young man back out to shop. Lols. He's afraid it'll never leave the shop again.

David

Yup, with discs should be no pressure when the pedal is released.

Thanks guys!

Soon all he'll need is side mirrors! Paint looks great now. Hope the brakes sort themselves out. I know I read on here a similar issue a few years ago, that ended up being something related to a valve mounted backwards, wish I could remember the details better! Keep us posted.

Ha ha Steve. I told him mirrors are a blessing but he's determined to stick with the shaved look.

Went out to the garage to finish up a fan shroud for Mike's Buick...Got a bit of work done but didn't get it finished, another one of those days that "King Arthur" is the victor!!! Oh well, should be some NASCAR stuff on the tube soon, and there's always tomorrow, right?

I think you've got your ponytail too tight............loosen it up and it'll go better.
