Why does my rear brake caliper turn but not retract?
Why does my rear brake caliper turn but not retract?
Like the title says, the piston on one of my rear calipers will turn with the cube tool, but won’t retract. Spent a good 20 minutes and probably got 50 full rotations, but nothing doing.
Why does my car pull to one side when I put the brakes on?
In cases like these, the car may pull to the opposite side when the brakes are applied. If the piston is stuck within the caliper, or the pad is stuck, the car can feel down on power (as if the parking brake is on). You may also notice the car pulling to one side with the steering wheel pointed straight, when cruising and not applying the brake.
Why is my brake proportioning valve stuck in one position?
If your brake system has not been previously worked on or suffered no brake leaks from the wheel cylinders, calipers or master cylinder, chances are the brake proportioning valve is stuck in one position, tripping the brake dash light.

What causes a brake caliper to stick to the pedal?
Caliper slides are grooves within the brake caliper that hold the brake pads when you press the brake pedal and let the pads loose when you let go of the pedal. However, with time the shims have an accumulation of debris and this causes them not to hold the brake pads tightly. This will cause the brake calipers to stick.
Why are my brake pads stuck in the brake bracket?
The brake pads have their guides, which should be lubricated for the brake pads to glide forward and backward on the brake caliper bracket easily. When dust and rust get collected on these bracket slides, the brake pads will get stuck in the brake pad bracket and push at the brake disc.
What should I do if my brake caliper is stuck?
Check the rubber boots and remove, clean, and lubricate the guide pins again. They can be a pain to remove when they have been stuck for a while – so a torch is a must to warm them up when trying to remove them. If your sticking caliper problem comes from the vehicle’s rear, there is a big chance of a problem with the parking brake.
Why does the piston turn but not retract?
The c-clamp will force it back in, through the threading. It would be like taking a water bottle and essentially hammering the cap back on. OP was doing it correctly, just not getting the results. That’s why I figure somebody did it wrong and just forced the piston back, destroying the caliper, essentially.
What does it mean when your caliper piston won’t compress?
Car owners might come across the issue of ‘caliper piston won’t compress’ in their vehicles. They may perhaps notice that their vehicle draws more to one direction when braking or the brakes are not releasing completely after they let go off the pedal.
Can a scan tool be used to retract the calipers?
Using a scan tool is typically going to be the manufacturer’s recommended method to retract the calipers to their service position to allow rear brake service or pad replacement. The scan tool is then used again to exit the service mode and automatically adjust the pads to the correct clearance after the rear brake service is performed.

How to retract the rear caliper piston with an integral parking brake?
How to retract the rear caliper piston with an integral parking brake. This style requires you to twist and push the piston in at the same time. They cannot be simply pushed back in.

Do you need to replace the brake caliper?
If on the other hand, the fluid didn’t shoot from the bleed nipple and the piston didn’t retract – your caliper is frozen and needs to be replaced. I would recommend replacing both on the same axle (both front or both rear), new pads and a brake fluid change.
How does a floating brake caliper work on a car?
I say a floating caliper is free to move, but it only moves by a few mm. The floating caliper uses a single piston which means to apply both pads, the caliper must move the outboard pad closer to the rotor. It does this by using the power of the piston to slide the whole caliper inboard.
Do you need a binding brake caliper for EPB?
Reactivating the EPB requires activating the parking brake a couple of times. A binding brake caliper is applicable to floating calipers which are fitted to most cars today.
Is there a way to compress the caliper piston?
There is a need to carefully diagnose and fix such issues right away as it may put your vehicle in danger. One of the main ways to compress your caliper piston fully is to take care of the brakes. If you top-up the brake fluid and replace the brake pads when required, then you might not run into any problems with the caliper piston.
Why are the rubber boots on my caliper not working?
The caliper bolts comprise of slides on them that require being lubed. The shielding rubber boots present on them helps to keep the lubrication in. But, sometimes these boots get tear away by the hasty mechanics when they are mounting new brake pads. As a result, the caliper piston fails to compress. SEE MORE:
