sherwood3333 Posted December 13, 2018 Share Posted December 13, 2018 adjusted brakes , car stops fine when street testing at 25 mph. when I go on hwy and run car, brakes pull hard left when I come into town and stop at signal lights. I have adjusted brakes several times, what may be causing this problem. thanks Link to comment Share on other sites More sharing options...
Fr. Buick Posted December 13, 2018 Share Posted December 13, 2018 Something in the front suspension? Or is one drum thinner than the other and therefor more prone to heat-fade? Link to comment Share on other sites More sharing options...
Ben Bruce aka First Born Posted December 13, 2018 Share Posted December 13, 2018 Does it return to even braking after "cooling " down? Have you pulled the drums for inspection since problem began? Ben Link to comment Share on other sites More sharing options...
RivNut Posted December 13, 2018 Share Posted December 13, 2018 Swap tires side to side. Had a separated belt in a tire that caused something similar. If nothing changes, swap drums side to side. How are the bushings on your brake reaction rods? 1 Link to comment Share on other sites More sharing options...
old-tank Posted December 13, 2018 Share Posted December 13, 2018 How new are the shoes, drums and hoses in the system? If the wheel alignment is off and "toed-out" if will get real squirrelly on hard stops from speed. 2 Link to comment Share on other sites More sharing options...
Bhigdog Posted December 13, 2018 Share Posted December 13, 2018 Do the easy stuff first by swapping things one at a time, side to side, to see if the problem follows then proceed accordingly..........Bob Link to comment Share on other sites More sharing options...
60FlatTop Posted December 14, 2018 Share Posted December 14, 2018 "Adjusted"? Is that all? If so you might have the wheel cylinder cups riding in the brown mud in a different location. If you have done a complete brake job and it still pulls, "someone" might have reused the old return springs. Bernie Link to comment Share on other sites More sharing options...
sherwood3333 Posted December 14, 2018 Author Share Posted December 14, 2018 car always polls after cool downs, all new brakes and drums, will pull brake hubs to look a everything, how to tell if return springs are bad. Link to comment Share on other sites More sharing options...
60FlatTop Posted December 14, 2018 Share Posted December 14, 2018 The springs usually look good and have paint on them, but you can't really know the age unless you put them on or have documentation. Pits in rusty springs can indicate changes in their metallurgy or a possibility of breaking. My policy is "when in doubt, change them out". The same goes for lining. I have seen aged lining with very little wear that doesn't stop well. It tends to lose the flexibility and gripping power with age. Fresh lining material can make a big difference. I would stay away from NOS shoes. Changes in braking that come and go depending on the car sitting for a while would make me suspect the rubber hoses. They will delaminate and trap pressure on the wheel side. I have disconnected them and run a piece of #10 electric wire through them to check. That can confirm a problem, but you might as well replace the hose at that point. Sometimes it is hard to find a listing for the rear brake hose on a Buick at the torque tube. I had to have one made for my '60. All new brakes and drums is pretty ambiguous if someone told you, actually, even if you did it yourself. Five people will give you five different length lists. 1 Link to comment Share on other sites More sharing options...
old-tank Posted December 14, 2018 Share Posted December 14, 2018 It may be time to get mad and make some hard stops (short of locking the brakes) from high speed in a safe location...could be some rough edges on the shoes. If no joy try backing off the adjustment 5 clicks on each wheel... a dragging shoe will heat, swell and lose effectiveness. 1 1 Link to comment Share on other sites More sharing options...
Volker Posted December 17, 2018 Share Posted December 17, 2018 Had the same Problem on my '57 Century. I got it fixed by changing all 4 springs to new ones. The springs in the right front brake were much stronger.... Link to comment Share on other sites More sharing options...
