  • Brakes: Brakes lock up in reverse

    62 G.T. Hawk, 4 speed, Twin Traction, drum brake, no power booster. Car rolls forward freely but wont move in reverse. Rear wheels digging in gravel driveway while trying to back up. Brakes serviced within the last 3 months included new rear shoes & brake fluid flush.

    I would go & try to help but he's around 200 miles from here so advise over the phone is the only option from me, that's why I figured on posting here. He doesn't have a floor jack or jack stands so the bumper jack is the only means available right now, which I discouraged.

    Possible causes- brake lines (possibly original) collapsed not allowing release, Brake shoe retaining pin broken or clip came off causing brake shoe to bind in drum? Any ideas or has anyone had the same experience & what it took to remedy?

    Good advice on the jack, Warren. I'm reluctant to even change a flat tire with just a bumper jack, even though I've done it numerous times over the past century. I would NEVER do brake work with just that jack. Best to have it towed to an equipped shop. Unless there's a forklift handy.
    And I would cast my vote for the shoe retaining hardware.

      Are the shoes installed in their proper position, front and back?

        Might be a broken spring, too.

        I wonder who did the brake service.

          Improper installation and/or improper adjustment.

          EDIT: The brake lines do not know (or care) if the car is going forward or backwards.

            If the shoes are bonded linings, I wonder if one came loose.
            I've had bonded linings come loose when my Corvair was parked for a year.

            1 1/2 ton aluminum floor jack $60 and 2 jack stands about $20 at Harbor Freight. I bought them years ago and they work fine.

              I'd suspect adjusted too tight.

                Brakes worked OK for three months then this just happened?

                Shoe retainers failed. Typical here in the rusty east for the pins to snap or the pin head get small enough to slip out of the retainer.

                Pull off drum to find real cause. Only solution. Let us know what was found.

                  I don't think the car was ever back east. It's in southern Arizona now & came from northern California prior. Brian was hoping to drive it on Saturday, IDYSD but now that looks like it wont happen. Sunday he leaves for a 3 week trip with his daily driver so unless something happens out of the blue, it will have to sit until he returns.

                      I've also seen wear in the backing plates where the brake shoes rub against the backing plate. There can be grooves worn in the contact spots especially at the bottom where the adjuster is located that cause the shoes hang up and grab when backing up. Bud

                        Just to clarify, were the brakes working normally and then suddenly began locking in reverse?

                          Yes, one day they were fine but yesterday they locked up in reverse. Moves forward ok but now it needs to back up.

                            Sounds like one of the rear shoes on one of the four wheels has come loose via a spring coming off or breaking

                              Something came loose. We can guess all day. The only way to find out is to pull wheels and drums. Should be relatively ease to figure out which one is locking just by backing up and looking for a dragging wheel.
                              If you can't get it to back at all, then jack up one wheel at a time and see which one won't turn that way.
