The rear disc brake piston needs to turn as it is retracted / compressed into the caliper.
Go to the parts store and tell them you need the brake cylinder retraction tool. Cost about 10 bucks and works for a variety of cars/vans.
It is a square with a couple of different teeth on each face, to align with the notches in the face of the brake piston.
Should work with a 3/8 drive ratchet. Clockwise facing the cylinder to retract. Have fun!
go to budget brakes
did you replace the master cylinder if so it has to be bleed frist
The Mercury Mountaineer has hydraulic brakes, not air brakes.
The easiest way I have found to do this is to use a "C" clamp on the brake cylinder and slowly squeeze it to retract the piston to the retracted position.
A wheel cylinder describes "Drum Brakes" - Drum brakes have one cylinder with two diametrically opposed pistons.
A 1991 mercury topaz has drum brakes on the rear wheels.
The ECU for the ABS brakes is attached to the Master cylinder for the brakes.
Conventional drum brakes.
The brakes on the Villager are as straight forward as the brakes on a 1965 Mercury. Only normal brake tools are required.
probably have a bad master cylinder.
you must turn piston clockwise as you push it in
just the slave cylinder, for your brakes.
master cylinder is sticking
Disc brakes at the top of the caliper Drum brakes at the top of the wheel cylinder
. If you have the 4-port master cylinder, the bottom ports go to the rear brakes & the upper side ports go to the front brakes.
If your brakes feel spongy, fill the master cylinder with brake fluid (make sure it is the same as in the master cylinder -do not mix dot 3 with dot 4 fluid) then try bleeding the line. If the brakes do not come back in firm, it may be time to repair or replace the caliper. Another common problem is the brakes lock up. What is happening is the piston does not retract and stays in the "applied" position. This puts a constant pressure on the rotor.
You bleed the skave cylinder just like your brakes. Pump a few times hold and open the bleeder valve and repeat.
Double check your rear brakes. Sometimes your self adjusting screw (star-wheel adjuster) is seized, or your wheel cylinder won't retract, or your parking brake cable is seized in the activated position.
Disc brakes may have been an option but it would normally come stock with drum brakes.
Brake cylinder repair is that wheel cylinder that holds the oil to keep your brakes running smooth on your back brakes. If you don't repair those you will mess up your rotors and your rims.
how to adjust rear brakes on 1997 tracer merc.
The 1.9 liter and 1.8 liter four cylinder engines used in the 1993 Mercury Tracer are NON - INTERFERENCE engines according to the Gates website ( they make timing belts etcetera )
underneath the master cylinder for the brakes in the engine bay.
front front - rear rear.
you either need to bleed your brakes, add fluid or get a master cylinder firstname.lastname@example.org
