slicknapier Posted June 9, 2009 Report Posted June 9, 2009 So I'm still having problems with my front passenger side brake sticking. I rebuilt the wheel cylinders yesterday thinking this was my problem and it's not. I've bled the brakes, both holes in the master are free of debris, and I've tried adjusting my brakes 20 times. I don't think it's and adjusting issue because the wheel cylinders don't compress back in. I can pump the brakes up then release them and the drivers wheel spins free while the passengers is still dragging. I had my wife push the brakes down without the drum on and the wheel cylinders do not compress back in. This thing is driving me nuts..Is it possible the returns springs don't have enough tension left to compress the wheel cylinders? They still seem stiff to me. Do I need to pull the cylinders back off and hone them out some more? Any advice is greatly appreciated. Car is a 51 plymouth. thanks guys, andrew Quote
Niel Hoback Posted June 9, 2009 Report Posted June 9, 2009 If you are sure you have good strong return springs, check the rubber hose to that wheel. It may be restricting flow internally. Quote
slicknapier Posted June 9, 2009 Author Report Posted June 9, 2009 rubber hose is in good shape. I cleaned it and made sure it was good. It doesn't seem that old either.. Quote
JIPJOBXX Posted June 9, 2009 Report Posted June 9, 2009 I don't know if this would work but could you just open the bleeder and see if shoes return to there proper position. This would be a test to see if it is the hoses or something back by the master cylinder. I know on mine I had a problem with my shoes not returning and I found it out just to be that I had put the shoes on wrong. By this I mean I didn't put the spacer washer that holds the shoes away from the backing plate. Somehow I had put the washers on the outside of the shoe and when I reinstalled them in the right location my brakes did not seize up anymore. Hope you get your problem fixed as I know its a bummer to chase problems around in our old cars. Jon Quote
Mr. Belvedere Posted June 9, 2009 Report Posted June 9, 2009 Helping the springs can you push shoes back in? You might check the backing plate where the shoes rub and see if there is excessive wear damage that they might hang up on, also put a little grease there and maybe where the clips hold them to help them slide a little better. Do they eventually let up and go back in or just remain out? Maybe inspect the hydraulic line back to the master cylinder for a dented or partially collapsed line that may allow the greater pressure from the master cylinder to the wheel cyl. but not so well the other way as return pressure is probably not as strong. I doubt the wheel cylinders are the issue. Quote
Mr. Belvedere Posted June 9, 2009 Report Posted June 9, 2009 Hi-temp wheel bearing grease should not liquify when hot I've been doing it for years based on a what a shop manuel said to do, and have never had a problem, besides its only a light little smear. Quote
BobT-47P15 Posted June 9, 2009 Report Posted June 9, 2009 And regarding the hose.....I had a rear hose on my car that looked perfectly good. Fluid would go thru it to the rear brakes.....but.....would not return very well as the INSIDE of the hose was collapsing. If I stopped extra quick, applied extra pressure, then it would lock up the rear brakes totally. I would then have to crawl under and open the bleeder to let out fluid so they would release. So.....just because a hose looks good, doesn't mean it works good internally. A new hose can be found at O'Reilly Auto and I think at NAPA stores. Not all that expensive. So, I guess a test would be - if the brake hangs up, let out a little fluid and see if it goes back down. If so, new hose is needed. Quote
desoto1939 Posted June 9, 2009 Report Posted June 9, 2009 As long as I have been doing brake jobs I have always used Lubraplate where the brake shoes pivot against the backing plate. This area always gets some wear and some times a little ridge forms run your fingernail in this are see if there is any indents or metal ridges, File them down smooth and get some lubraplate on these areas. Also oil the felt washers but not too much they should be damp and not dripping with oil. Did you check the eccentrics where the shoes attach. Are there any ridges these need to be smooth. Sound then as if a brake hose. rich desoto1939@aol.com Quote
slicknapier Posted June 9, 2009 Author Report Posted June 9, 2009 where exactly are the spacer washers? The ones on the bolts for the wheel cylinders or where the shoe makes contact with the backing plate? If I bleed the wheel cylinders the shoes will come back in. I can't push the shoes back in without bleeding the cylinders. Quote
slicknapier Posted June 9, 2009 Author Report Posted June 9, 2009 well I did all of the above. I made sure the shoes can slide back and forth and they do with ease. I still can't get the wheel cylinders to release... Quote
BobT-47P15 Posted June 10, 2009 Report Posted June 10, 2009 (edited) I hate to keep beating a dead hose, but......... Front hose, purchased at O'Reilly Auto store. Rear hose in the center.......... New front cylinders......... New rear cylinders........ Edited June 10, 2009 by BobT-47P15 Quote
slicknapier Posted June 10, 2009 Author Report Posted June 10, 2009 Bob, I some how missed your post earlier. I will look into replacing my rubber lines. thanks Quote
