bubba Posted June 9, 2014 Share Posted June 9, 2014 Everything is new. Pulls to right but gets better when warmed up. Had surface of front drums cut and that just about fixed it till next time I drove it. A mechanic who worked on these cars told me to put cast iron drums on front and that this was a common problem with aluminum. Any NOS cast drums around or can somebody recommend a good supplier of replacement drums?I have spent a lot of time trying to get the master cylinder to work correctly and finally ended up with a brand new dual master.I didn't change anything that can't be put back to original. It almost works too well now. Need seat belts next!Car pulled the same way with the original master.thanks Link to comment Share on other sites More sharing options...
TexasJohn55 Posted June 9, 2014 Share Posted June 9, 2014 If the shoes are new, replace both front rubber brake hoses.. Link to comment Share on other sites More sharing options...
Larry W Posted June 9, 2014 Share Posted June 9, 2014 Just a thought, but I wonder if a worn part in the front suspension on either side might be causing your condition. Perhaps a control arm bushing could be worn, and when you apply the brakes, it shifts position enough to cause it to pull to one side. Upon acceleration, it shifts back into proper position and you go straight. This may be accompanied by a slight click or snapping sound. It might be worth a thorough investigation.

old-tank Posted June 9, 2014 Share Posted June 9, 2014 That is NOT a common problem with aluminum finned drums. Many reasons for pulling: brake hoses, bleeding deficiencies, contaminated shoes, poor adjustment of shoes (may need to seat...check adjustment every few day for awhile), wheel alignment (excessive toe-out), should have a short and long shoe --- install short shoe toward the front ( I have seen alternate combinations and they all caused pulling)...Willie Link to comment Share on other sites More sharing options...
Guest j49plymouth Posted June 9, 2014 Share Posted June 9, 2014 Have you replaced your wheel cylinders? front and rear? A frozen cylinder will cause a pull. Link to comment Share on other sites More sharing options...
bubba Posted June 9, 2014 Author Share Posted June 9, 2014 TJ55 yes , both shoes and hoses are new. Larry W. my friend mechanic was checking that last night. He'll have to come back.Old tank , j49- will check some of your suggestions. Everything was replaced except drums. Front shoes were changed twice. There was kind of an oxidation film on them so that is why they were changed and the drums resurfaced.Thanks to all that replied so far. Link to comment Share on other sites More sharing options...
dei Posted June 10, 2014 Share Posted June 10, 2014 Bubba,Something else you might want to inspect would be the steering coupling at the power steering box. I had one that eventually cracked and there was a lot of slop in the steering. Admittedly it was both ways but with a slightly out of adjustment front brake it could enhance the pull. These 4 thousand pound cars do tend to follow the slant in the road especially with bias ply tires if you have those.Just a thought. Link to comment Share on other sites More sharing options...
bhambulldog Posted June 13, 2014 Share Posted June 13, 2014 a leaking cylinder, inappropriate adjustment ....If it's pulling to the right ... I would be checking the leftIt might not be the front. It could be the rear brakes ....It's NOT due to aluminum drums...Iron drums are not immune from this problem.. Link to comment Share on other sites More sharing options...
