T he front brakes on my 65 BelAir are pulling to the left. I have drum brakes front and rear. It has self adjusters on all wheels. I have installed a power booster.I have replaced the mastercylinder,all brake lines,all wheel cylinders,brake shoes and spring kits. I have had the drums turned and pressure bled the system several times. I have switched the shoes and springs from left to right and it still pulls to the left. I have adjusted the brakes with the right side a little tighter and it still pulls to the left.I am thinking of putting braded stainless lines from the frame to the front wheel cylinders. I have had the new rubber lines off and can look through them and can see no problems. Any thoughts no what might be the problem? Thanks Russ

It could be an issue with the suspension. How are the control arms and bushings? Have you had the alignment checked?

Had that problem with my 65 vert sometime ago also. After doing the complete replacement of the drum brakes i found the strut rods had been loose at the control arms,for awhile by the looks of the fasteners.so when i went to stop, it would pull.. so some locktite on the new fasteners with a new set of bushings and alignment and she stops pretty straight.drum brakes from back in the day will never be a perfect straight stop, but can get them real close.

When turning the drums an issue can arise where the surface contact of the linings to the drum can change, to correct this back in the day we would arc surface the linings to restore full lining contact. If the drums took a different amount of resurfacing left to right, a pull can develop.

Thanks for the info. I had replaced the all the front bushings and steering linkage before the brakes. I also had the front end alinement done. The car does have a slight pull to the left going down the road. I am thinking of having the alinement redone.

A pull to the left on braking indicates a less efficient braking effort on the right side. Focus your attention on the right side front, as rear brakes can, but seldom do, cause significant pulling. Look for grease on the drum or lining surface, and recheck the adjustment.

RATHD,
Everything I was going to suggest has been mentioned....except one thing. Try switching the front tires side to side. Sometimes a tire problem can cause pulling to one side.
Let us know what the solution is. Bill

It sounds like you are no stranger to auto repair. Sd o this may sound bad but do you have a primary and secondary shoe on each side. I have seen where people put both primary on one wheel.

Thanks for the help. I have switched every thing from right to left and still have the same problem. I have tryed adjusting the right brake thighter than the left but still have the same problem. I have tryed a hard stop in gravel and all 4 wheels lock up at the same time. When i stop regularly the left wheel slides befor the right. I am still thinking about replacing the front brake hoses again with stainless ones. The brake system on this car is not very complicated but it has me baffled.

Does yours have a brake fluid distribution block or valve in the system. Yea I may be reaching some but then it can be the little things...Ed

Do the fronts also have self adjusters like the rear? I suspect yes. If yes those adjusters are left and right specific. I guess that probably is not the issue because if on the wrong side it would adjust pretty fast and it would not seem as close to normal as it sounds.

One other thing which you visually inspected already. I had a near impossible side-to-side issue which turned out to be one soft line was worn out and was expanding enough to lessen the braking on that side. I didn't notice it by sight. In that case however the brake pedal was going down more than normal as well.

Whitetail also mentioned the difference in the shoes. I didn't see a response to address that so I thought it might be worth mentioning again. I would have also thought what jkTucker mentioned was high on the probability list as well.

Hope you figure it out,
Scott

The brake shoes are on correctly and it does have self adjusters on all wheels. It does not have a distribution block.I am going to replace the front brake hoses again. They are new but i got them from auto zone.I am replacing them with stainless ones from classic industries. Thanks for all of the advise. I will post if the new hoses help.

I was wrong it does have a distribution block.I was thinking of a combination valve. I have ordered a new block with the new front brake hoses.The block is the only thing that i have not already replaced.

On the self adjuster comment I meant one is left hand thread and the other is right hand thread. I was thinking of what would happen if you happened to get 2 of the same PN. If you have things apart again you might want to verify the adjusters.

It might be a long shot but another thing that made me think of that possibility was that you wrote you switched "everything" side to side. Well the the adjusters cannot be switched side to side without being wrong so if nothing changed maybe they are the same PN. Also I understand if "everything" was with the exception of the adjusters.

How are the strut rod bushings? I had that problem on my old 65.

I did not switch the adjusters and they are working correctly. The front suspension has been completly rebuilt also. All the braking system is new. This is why it is confusing why it still pulls to the left.Thanks for all the suggestions.
