Pulling to the right!
Posted by: Monza ()
Date: July 08, 2018 05:47PM

Hello everyone! Thanks to everyone who helped with the idle issues! I've got a new problem. When I got the car the old owner said it pulled to the right. I rebuilt the brakes with all new stuff. Still pulls to the right. Do these cars have purporting valves? Could there be something I missed?

Assuming the brakes are adjusted correctly, I would have to check the alignment, ball joints and tie rod ends.

Normally LEFT brake is not functioning!

Most likely sticky wheel cylinder....

NEXT... is Front end tight? no play in the wheel?

You can check "toe-in" easily at home....

Since it's NEW to YOU..

Get a friend...

have them count the turns of the Steering wheel and "Center" AS YOU watch the Steering arm to make sure it's centered...at the same spot.

Now look down the side of the body and make sure they seem straight... or no more than a little bit pointed / "toe'd" IN up front..

If not get back to us for instructions.

I'll check the alignment. Like I said, the only thing I reused on the brakes was the steel lines, which were in excellent shape. New cylinders and soft lines all around.

Over the years I've run into a number of things that cause this, and learned a few things from posts here.

Did you install new brake shoes, brake springs, check the drum diameter?

My last go round was a real oddball. New shoes and the adheasive from one shoe oozed out onto the lining and got into the linings and drum. Much to my amazement brake cleaner removed the mess and the brakes worked fine after I cleaned them.

Mine was pulling to the right...I reset the toe in...was in specs but made it closer to the min. The thing that cured it was I converted over to a duel MC and the brake did not have the slight free play between the brake pedal and MC. I adjusted in a little more play in the brake pedal as I had NONE and that took care of the pulling to the right.

Of course, several things can cause pulling to one side...even worn wheel bearings.

Having built 3 street rods, one frame off, the other two close to that, I should have known better when I changed the Master Cylinder...shame on me.

Check the alignment, especially the "control rod" (Item 19 in Clarks here)

This control rod reacts to the braking force, and if its adjusted wrong, or the bushings are loose, the control arm comes backward and causes a pull to the side. The right one would be the key one to look at for a pull to the right. I had the same problem, and I adjusted this rod to push the right control arm forward slightly and I tightened the play up between the bushings, and it made a radical change for the better.

Do these cars have proportioning valves?

Did you indeed put all new stuff including shoes, drums turned, hoses, wheel cylinders, brake spring kits, self adjuster kits, cleaned and lubricated shoe contact points on backing plates. If this is the case you have a bleeding issue (air in L side), assembly error, adjustment error, a faulty part perhaps, maybe an alignment issue. I have had a couple recently that spring and adjuster kits fixed pulls (the old parts looked ok). One that I had to smooth the backing plate contact points (a couple small high spots) and lube again. Small thing can make a difference. You can try to isolate issues to a point by swapping swappable parts to see if issue swaps (only shoes, drums, hoses, and spring kits can be swapped). Generally a pull one way is an issue with the other side of the car not working or working weakly but shoe not returning from sticking to backing plate can cause pull on that side. I would re-bleed, replace any non replaced parts and look very closely at my install. I might next swap some parts side to side. Alignment issues might be next. If the right front is pulling it is possible that wheel is adjusted farther back than the left.

Monza,

Does it Only pull to the right when you apply the brakes?

Front or rear wheel locking up? Jam the brakes hard to see. Usually you can get a pulling brake to lock up before other brakes., Rear wheel locking causes are similar to fronts but if the R rear e-brake cable is not fully releasing could hold the R rear shoes out some causing early engagement.

You want them even = adjusted the same. So readjust all your brakes and test them again to see if it pulls.

It's the front that's pulling. It pulls hard enough that it will take the steering wheel away from you, but only when you hit the brakes even at low speeds.

One of your front brakes is doing more "work" than the other... the direction it pulls is the one doing the most braking.

Likely causes: 1) uneven brake adjustment (opposite side from pull is not adjusted tight enough or pulling side is adjusted too tight) 2) contamination on brake linings on opposite side of pull, 3) wheel cylinder on side opposite side from pull sticking.

Cars with proportioning valve is for front to back bias adjustment AFAIK

Good luck.

Don't ask me how I know, did the shoes get installed correctly with the long and short material shoes in the correct place?

Another thing that will take the steering wheel out of your hand is washing your car.. washing it, really?..then driving it pretty soon after that. I had to return home many times right after washing it until I put two and two together. Having enough credits in math minus one 3hr course to teach it in HS, that should not be a problem.

This is how that occurs. I had removed the rubber stoppers when I rebuilt the brakes, did not put them back in thinking I would re-adjust the brakes after driving it....it did fine so they were not put in. Water gets in the drum and if ANY liquid other than graphite gets in the drum....you almost lose total control of the car pulling to the side.

As I stated earlier about fixing my pull....

I am thinking by adjusting the clearance in the brake pedal to MC took my pulling away as the brake lining/fit is different in the front wheels and the right brake was probably slightly appied causing the pull.

Problem fixed. I copied the way the brake shoes were installed when I rebuilt the brakes. I didn't know about primary and secondary brake shoes. I put it up and stands and had the drums off and as soon as my dad walked by he spotted they were backwards. Swapped them around and now they work great. Thanks everyone for all your helpful suggestions and ideas!
