      Siphon 2 / 3 of the brake fluid out of the master cylinder reservoir.

      Release the parking brake.
      Loosen the lug nuts, then raise and safely support the vehicle.
      Remove the tire and wheel assembly.
      Install two wheel nuts to secure the rotor in place.
      Using a large C-clamp, position the clamp on the caliper housing and against the back of the outboard pad and lining. Tighten the clamp slowly to press the piston into the caliper bore.
      Remove the bolt attaching the hose fitting, only if the caliper is to be removed for overhaul. If only the pads are to be replaced, there is no need to disconnect the hose fitting.
      Plug the opening in the caliper and the pipe to prevent fluid from seeping out and contamination.
      Remove the Allen head caliper mounting bolts. Inspect them for corrosion and replace them if necessary.
      To install:
      Coat the bushings with silicone or grease.
      Install the caliper and brake pads over the rotor, in the mounting bracket.
      Install the mounting bolt and sleeve assembly, then tighten the mounting bolt to 28 ft. lbs. (38 Nm) for 1982-84 models and 38 ft. lbs. (51 Nm) for 1985-96 models.
      Measure the clearance between the caliper and the bracket stops. If needed, remove the caliper and file down the ends of the bracket stops to provide clearance. The caliper may appear to be touching the lower abutment and still not be interfering. The caliper should slide freely on the mounting bolt and sleeve assemblies.
      Install the brake hose to the caliper. The brake hose fitting should be tightened to 33 ft. lbs. (45 Nm). Always use new fasteners.
      Install the wheel and tire, hand-tighten the lug nuts. Lower the vehicle, then tighten the lug nuts to 100 ft. lbs. (136 Nm).
      Top off the brake fluid.

    Why do my rear brakes lock up
    • edwardeverett4u
      2/27/2013 edwardeverett4u
      on my 1997 ford Taurus all 4 of my brakes locked up every time I would release as I drive and kept getting worse and worse. then all 4 brakes locked up and car wouldn't move. it turned out my master cylinder was bad and building up too much pressure. I had changed it but I also had to change all 4 rotors and all 4 brake pads. so hurry up and fix it because the longer you drive the more damage you will cause.

    My Brake fluid is Leaking
    My brake fluid reserve bottle is always empty.I will put brake fluid in it,and wait awhile then go back out to check it,and the fluid has leaked somewhere and is all over my driveway.. Why? I see no holes or cracks in the reserve bottle..Now when i use my brakes ...

      The leak will not be the reservoir, it will be a wheel cylinder or a rusted brake line that has a pin hole. Someone has to check all the brae lines and brake components. if the brake fluid is all pver the driveway then it will not be difficult to determine the cause if an experienced mechanic looks at it. For you yes it will be difficult or impossible.

      Safely raise and support the vehicle. Remove the wheel and do an inspection. It could be one of the bolt ( there are 2 bolts ) might be not tighten to the proper torque.
      OR stop by a known good brake shop for a free inspection.

      Check the brake caliper, there are 2 bolts.

    How to get to bolts inside car for brake booster

      1991-99 Vehicles
      For 1994-99 vehicles with ABS, after bleeding the brake system you must perform an "Auto Bleed" sequence, using a Tech 1® or equivalent scan tool. If you do not have access to a suitable scan tool, your vehicle will probably have to be towed to a shop with the proper diagnostic equipment to have the procedure performed.

      The booster can be removed from the vehicle without removing or disconnecting the master cylinder. However, if both the booster and master cylinder are to be removed, remove the master cylinder first.

      Disconnect the negative battery cable.
      Detach the booster vacuum hose from the vacuum check valve.

      Unfasten the master cylinder attaching nuts. Separate the master cylinder from the booster. Move the master cylinder forward just enough to clear the booster studs. This will flex the brake pipes slightly, so be very careful not to bend or distort the pipes.
      Remove the acoustical barrier from the booster studs, located inside the passenger compartment, under the instrument panel.
      Unfasten the booster attaching nuts, from inside the vehicle.
      Remove the booster from the brake pedal. Tilt the entire booster slightly to work the pushrod off the pedal clevis pin without putting undue side pressure on the pushrod.
      Remove the booster from the vehicle, then remove the gasket.

      To install:
      Place the gasket on the booster. Position the booster in the vehicle.
      Attach the booster pushrod to the brake pedal. Tilt the entire booster slightly to work the pushrod onto the pedal clevis pin without putting undue side pressure on the pushrod.
      Install the booster attaching nuts and tighten to 15 ft. lbs. (21 Nm).
      Install the acoustical barrier to the booster studs, located under the instrument panel.
      Position the master cylinder to the booster and secure with the retaining nuts. Tighten the nuts to 20 ft. lbs. (27 Nm).
      Attach the booster vacuum hose to the vacuum check valve.
      Connect the negative battery cable.

      There is no magic answer here. They are awkward to get to. You will need universal joint sockets, deep or semi-deep preferrable and a few 3/8" extensions. There are no rules. You use any and all tools at your disposal to make a connection to the retaining nuts, whatever works. short wrenches, 1/4" drive flexhead ratchet, long 3/8" extension with flex socket. Diagram........uhhhhhh, nope.

      Brown brake fluid is a symptom of having rust in your brake system. This is a common occurance in older vehicles, and should not cause problems. You could bleed the brakes with fresh fluid to remove the old...

    Just changed the brakes and rotors. But the car is shaking now. What can it be??
    Everything is tight. Do you think it is the tires.

      Need more information - when does the shaking / vibration occur? Only during braking? If yes, then recheck the wheel bearings / front hub bearing to make sure they are correctly tightened. If tightened OK, then check the front hub / bearing condition for excess play / looseness. Also, check the front suspension bucshings for excess wear / play.
