Steve Heller (aka ALLEYCUSTOM) [ View ] [ SMHELLER@COMCAST.NET ] [ Car Ads ] [ Blogs ] UMATILLA, Florida (352) 483-5515

MY '40 FORD HAS (POWER) DISC BRAKES ON ALL FOUR CORNERS. OCCAISONALLY AT LOW SPEED ONE OF THE CALIPERS SEEMS TO GRAB. IT DOESN'T CAUSE THE CAR TO PULL OR LOCKUP, OCCURS RANDOMLY, BUT IS LOUD (AND ANNOYING). I HAVE NOT FOUND ANYTHING OBVIOUS, CAN'T SEEM TO DUPLICATE THE CONDITION WHEN SOMEONE'S HANDY TO WALK ALONG SIDE AND AT LEAST NAIL DOWN WHICH CORNER. ANY SUGGESTIONS? THANX

Posted by Willys33  -  12/10/2007 08:18 PM Several things come to mind. First, is there anti-squeal backing on the pads. This is usually red RTV. Second, baring a hose that is old and maybe closing up I would take the pads an bevel the leading edge so they don't grab and chatter.

WHY DON'T YOU BUY IT AND I'LL HELP YOU FIND THE GRABBING BRAKE. THANX, STEVE BACK TO THE BRAKES; I CAN'T PREDICT WHEN IT'S GOING TO HAPPEN. MAKES IT TOUGH TO CHASE. ALLEYCUSTOM [ View ] [ Email ] [ Blogs ] [ Car Ads ] UMATILLA, Florida   Posted by dmtm125  -  12/11/2007 12:36 AM could be a bad caliper sometimes the fiber pistons get hot and swell causing them to bind. if it has the steel pistons they usually dont bind . maybe go drive it a little while. come back and squirt the calipers with water and cool them off see if it binds Doug Mars [ View ] [ Email ] [ Blogs ] [ Car Ads ] Okeechobee, Florida Charter Member since October 2007   Posted by Rods & Customs by Leon  -  12/11/2007 02:49 AM Sounds like it could also be a bearing issue... Rods & Customs by Leon [ View ] [ Email ] [ Blogs ] [ Car Ads ] Highlands, Texas Charter Member since May 2004   Posted by dixie  -  12/11/2007 04:22 AM Explain that to me i don't under stand the bearing issue,i've had alot of bad bearing which did not effect the brakes,just curious. jim grace [ View ] [ Email ] [ Blogs ] [ Car Ads ] dade city, Florida Charter Member since January 2006   Posted by Rods & Customs by Leon  -  12/11/2007 05:03 AM AT LOW SPEED ONE OF THE CALIPERS SEEMS TO GRAB.(That tells me there is some slight resistance) IT DOESN'T CAUSE THE CAR TO PULL OR LOCKUP, OCCURS RANDOMLY, BUT IS LOUD (AND ANNOYING). I HAVE NOT FOUND ANYTHING OBVIOUS, CAN'T SEEM TO DUPLICATE THE CONDITION. One grinding noise you can get is from the bearing it self and/or the hub movement can force the rotor into the pad harder on one side of the assembly, If you can't duplicate it with the pedal theres some other pressure causing the friction........One other option is a small piece of gravel getting wedged but that would be more constant. One thing I do suggest with any odd brake noises or questions in general.... dismantle it all until you find the problem, It can really suck if you have to find it the hard way "on the road" Rods & Customs by Leon [ View ] [ Email ] [ Blogs ] [ Car Ads ] Highlands, Texas Charter Member since May 2004   Posted by Crazyhorse Rod Shop  -  12/11/2007 01:21 PM make sure the caliper is lubed first, then check bearings like leon suggested. these are the 2 most common problems. dont poke the porchdog........he bites [ View ] [ Email ] [ Blogs ] [ Car Ads ] BLUFF DALE, Texas Charter Member since March 2003   Posted by dixie  -  12/11/2007 07:14 PM Well thanks i learned something new,seems mine always ends up in the master cyl.
