Why does my wheel cylinder keep leaking?
Internal corrosion is the chief culprit of leaky wheel cylinders. Brake fluid, by nature, is hygroscopic–meaning that it absorbs water. If the fluid is not changed for several years, the moisture in the fluid rises to considerable levels. These holes allow fluid to leak past the pistons and out to the environment.
How do you know if the wheel cylinder is leaking or bad?
One of the first and most distinct symptoms of a bad wheel cylinder is a “mushy” brake pedal. If the wheel cylinders are leaking, their ability to pressurize and extend the piston may be compromised. This makes the brake feel strangely soft or mushy as if the brake slowly sinks to the ground when it is depressed.
Can a leaking wheel cylinder be rebuilt?
Rebuild/Replace One Or Both? Wheel cylinders should be rebuilt or replaced in pairs. Even if only one is leaking, it’s advisable to rebuild or replace both sides. If you find that only one is rebuildable, it’s OK to rebuild the one and replace the other with a new cylinder.
Are there any problems with the Toyota Corolla?
This may lead to harsh transmission shifting, the engine stalling, or the engine failing to start.

What causes a Toyota Corolla airbag to rupture?
Premature Passenger Airbag Propellant Failure: When the passenger airbag deploys, there’s a chance it’ll rupture and allow metal fragments to fly through. This happens because the propellant rapidly degrades over time due to unstable temperatures and excessive humidity.
What causes engine to stall on Toyota Corolla?
Cracked Engine Control Module (ECM): The circuit board inside the ECM on some of the Corollas in this generation is prone to cracks. This may lead to harsh transmission shifting, the engine stalling, or the engine failing to start.
