How can i compress the piston on the caliper rear brake?
Lubricate the boot with rubber grease to avoid twisting the piston boot. If the piston boot is twisted, back it out so it is positioned properly. I hope this helps. . If you have no additional questions please remember to rate my service before exiting the site so I can be credited for my time.
How does the rear brake caliper work on a car?
[b]If you look at the piston for the rear brake caliper, you’ll see some sort of feature on the face of the piston. This where a tool is used to rotate the piston back into its bore, while at the same time compressing the piston.
How does a rear disc brake system work?
There are two different kinds of rear disc brake parking brake systems. Yours is undoubtably the kind of system that uses a lever attached to the back of the calpier to actuate a mechanisim within the caliper that pushes the piston and ultimately the brake pads, holding the brake. That mechansim automatically adjusts itself as the pads wear down.
How do you turn a piston back into the bore?
If that doesn’t work, and the piston has notches in it, use a pair of plyers to grab onto those notches and turn the piston back into the bore. Make sure the cover is off the master cylinder reservior. [b]If you look at the piston for the rear brake caliper, you’ll see some sort of feature on the face of the piston.
How do you compress the front brake calipers?
Turn the screw on the clamp to compress the brake piston then release the clamp. The piston will remain compressed allowing you the fit the housing over the new brake pads. Loosen (don’t remove) the small bleeder valve on the back of the brake assembly while you apply hand pressure to the piston.
How many pistons are in a rear brake caliper?
Also, some rear single piston calipers have a mechanism on the back for the parking brake. Dual (2) Piston Calipers are usually sliding calipers with brackets, but some 2 piston calipers are fixed position with opposing pistons – one on the inboard and one on the outboard side.
When do you release the front brake calipers do you?
Do not release the caliper assembly until you have re-tightened the bleeder valve – to do so will **** air into the brake line and require you to bleed the system. If you have disk brakes, and you cannot fit the new brake pads in the callipers?
How does a piston work on a brake pad?
These pistons extend outward in a counter-clockwise direction to apply pressure on to the brake pad while braking. With this particular vehicle, the pad braking material had worn off and the brake pad plate was making metal-to-metal contact with the rotor thereby ruining the rotor.
