All new front brake parts, steel and rubber lines, drums, shoes, wheel cylinders and spring kits. The car brakes well, but the right front vibrates heats up and starts pulling to the right after several miles. I've double checked everything except drum out of round so I'm gonna swap sides with the drums and see if the problem follows to the left, any thoughts or ideas ? Later Kirk..
Did you clean the drums with brake parts cleaner? Check the bearings as well. I have had trouble with bearings in the last year and found that even National bearings are made in China. On mine the races were wearing and found metal slivers after only about 50 miles. Good idea about checking for out of round. I go a step further and have rotors and drums checked before initial use. I have had a drum out of round before. China again I guess.
I cleaned drums with brake clean and put in new bearing last year, just pulled hub and checked bearings, they are good
Ok, I think I figured it out, when I finished the brake job I noticed as soon as I pressed the pedal the rear brakes would lock up, so I drove it anyway thinking it was an adjustment issue. After a couple short trips around town and leaning on the pedal pretty hard the back brakes stopped locking up and then the right front started vibrating and overheating. That brings me to today, I checked the bearings and swapped drums left to right and the problem stayed on the right. So I'm thinking its the porportioning valve... What do you think? Later Kirk...
Did you check the right side for proper shoe placement? (Primary and secondary) just throwing out stuff I would look at as I run drums on my GS. I am guessing you left the original steel lines on? Did you try bleeding the fronts to see what the pressure is like side to side?
Yes, took both drums off and double checked everything yesterday.. everything new from master cylinder to a the wheel on both sides...
When you jack up the right front does it spin, is it tight or plain locked up? If its tight or wont budge, crack the bleeder open on the wheel cylinder. If its still locked up, you have a new defective wheel cylinder. If it frees up, lock up the wheel again and crack the steel line going into the flexible hose. Keep working your way upstream
I need a porportioning valve, but all I can find is disc/ drum and I have drum/drum. Will a disc/ drum work ? Thanks, Later Kirk
drum brake cars don't typically have a prop valve. your issue lies within drum. double check all the springs and adjustment
The drum cars have a distribution block. It is located in the lower left side, under the firewall. That probably isn't your issue. The only "guts" in it is just for the "brake" light on the dash.
