Parking Brake sticking 2014 Toyota Sienna LE FWD

2014 Toyota Sienna

Changed rear rotors and brakes and now wheel won’t spin in reverse. Parking brake is engaged in reverse. Replaced all springs/hardware on parking brakes and used PBBlaster to make sure the cable wasn’t getting hung up. Tried to drive the car several times and parking brake is definitely on in reverse. Adjusted the adjustment wheel so that the brakes are compacted as much as can be and the hub spins fine forward but stops immediately when spun in reverse. I even put the old rotors back on thinking that would solve it however still acts the same. In the end, by taking out the adjustment wheel spreader the car works, however I have no parking brake and it will not pass state inspection this month without it. I’m at a loss and feel as if I’ve tried everything.



This may sound odd to you but I have seen this once before. It turned out the brake shoes were install improperly. Let me see if I can describe what was going on. The brake shoe material is a different size for two of them. The actual external shoe (metal part) is the same on all four per say. But there are two that the shoe material is shorter then the other. Looking at just one side with two short shoes or one side with two longer shoes would be hard to notice. And the difference if difficult to notice at all until you set one directly on top of the other for comparison. This would be what I would recommend you check first.
