yes
MOISTURE IN YOUR BRAKE FLUID. FLUSH SYSTEM WITH NEW FLUID.
Corrosion? Contaminated brake fluid?
Age, moisture in the brake fluid, normal wear, etc.
A car has to have brake fluid to allow for the effective operation of the brakes to stop the car. When we apply pressure to the brake pedal, brake fluid, which is largely incompressible, will transfer that pressure to the pistons that operate the in the calipers or the pistons that operate the brake shoes. Further, the fluid must be of the correct type for the system in which it is used. The continued safe operation of the brakes may be compromised by the wrong fluid.
your breaks will not work with out it. break fluid is part of the Hydraulic system It runs to the brake lines and into the calipers Where it pushes on pistons that apply pressure to the break rotor making the car stop.
No. If your calipers are leaking, they need to be replaced. Calipers leak because they're worn out, or because you didn't change the fluid and it corroded the inside of the piston bore.
Sticking brake calipers. This can be caused by moisture in the brake fluid which will cause the calipers to rust. Replace the calibers and replace all the brake fluid. It can also be caused by driving with your foot on the brake.
leaky wheel cylinders or calipers
If the parking brake is connected to these calipers they thread in clockwise special tool is available (not expensive) at Sears or auto parts If parking brake is not connected to these a "C" clamp should work to retract piston release the bleeder screw then either push them in or use a c-clamp to push them back in... this will waist a significant amount of brake fluid so make sure you have some handy I generally use a "C" clamp, but you can use whatever you have that will put pressure on the calipers to retract. The calipers move slowly and more pressure won't speed the process by much. If the calipers are moving, just keep even pressure on them.
Any fluid other than brake fluid will ruin the master cylinder, abs unit, brake hoses, and calipers.
check brake hoses. check brake fluid condition, if fluid is contaminated or mixed with wrong fluid, calipers can lock-up or stick. check caliper bolts, hardware, caliper brackets. replace if broken, bent, or missing.
bad calipers change them yesterday not tomorrow
