Disc
Brakes of All Makes:
Before pushing the calipers back, open the bleeders. Push the old fluid
out, not back into the master cylinder. Use the proper lubricant, including
anti-seize compound on metal to metal surface and silicone based product
on metal to rubber surface. Use the slowest speed possible when machining
rotors or put a non-directional cut on disc. Clean the disc thoroughly
after machining to remove fine particles of metal.
Corvettes
From 1962 to 1982:
Rotors run-outs are crucial on these cars. On the fronts, machine the rotors
with the hubs attached. On the rears, machine the rotors on the car if
possible. When installing new rotors, always check run-out. The easiest
method of bleeding I have found is as follows: open the bleeders one at
time and work on something else. Don't let the master cylinder go empty.
If you try pumping, you'll just agitate the air in it and it will stay
trapped for days.
1984 to 1986
Corvette:
In order to bleed the rear brakes, the front of the car must be higher
than the rear. This is in order to have the bleeder screws at the high
point of the caliper.
Ford Problems:
Watch for seized rear wheel cylinders. Check them by applying the brakes
slowly, while a drum is removed. Insure both shoes move. With regard to
Aerostar emergency brake release. Along the left side of the brake handle,
there is a handle shaped like a quarter moon. Using a small screwdriver,
push on the top of the release. After the rear brakes are completed and
adjusted, the emergency brake adjust automatically the first time the handle
is applied.
F-Series Truck:
With a spongy or sinking brake pedal, the problem seems to be a bad master
cylinder. Before replacing the cylinder, check for pressure low through
the ABS dump valve into the accumulator. If the vehicle pulls to one side
when braking be sure to check the radius arm bushings for movement.
Crown Victoria
& Grand Marquis from 1992 to Present:
The parking brake shoes are in the hat part of the rotor. Remove the rear
rotors. To do this, patience is the key. Back down the adjusters for the
parking brake. Apply even pulling pressure on the rotors and tap lightly
on the hub surface to allow the shoes to release. If forced, damage to
the backing plates and shoes will result.
Jaguar
At the front end, the caliper mount and steering arm share the same bolt.
Before removing the bolt, pay particular attention to the placement of
the washers. If not put back together properly, a toe problem in the alignment
will occur and you will be buying an expensive set of tires. |
