Tip & How-To about Motorcycles

Disc Brakes: Helpfull hint.

Whenever removing a wheel with disc brakes or dismounting a caliper from the bike and the brake system is still plumbed, it is wise to place a sliver of wood between the disc pads.

This will prevent the pads from slamming together when you bump the hand lever or lean on the foot lever...because that will happen.

You would then have a very difficult time trying to prise the pads open to clear the disk. You are fighting tremendous pressure and damage will be the result. Or a complete bleed of the system to get the pad pressure released.

Replacing front brake pads 2001FXST


Front Brake Caliper: All But FLSTS/FXSTS

Remove the front master cylinder reservoir cap to be able to check the fluid level as the caliper pistons are pushed back into the caliper because the fluid level may rise more than the 1/8 in. (3.2 mm) from the top level and you may have to remove some excess fluid if it does so. THEN loosen but do not remove both pad pins with a 12 point one quarter inch socket. THEN remove both metric caliper mounting bolts and remove the caliper from the front forks and brake disc and pry the pads back to force all four caliper pistons into their bores. THEN once the pistons have been retracted, remove the pad pins and the brake pads.


Although the front and rear brake calipers except FXSTD models, use the same exact brake pad set the FXSTD does not and the FXSTD rear pads have a vertical slot cut into the pads. Be sure NOT to substitute front and/or rear brake pads for the other on these bikes. On the right side of the vehicle the pad with the two tabs installs on the inboard side of the caliper and on the left side of the vehicle, the pad with the two tabs installs on the outboard side of the caliper.


THEN install new pads into the caliper noting that the curved portion of the pad faces to the rear of the bike, and loosely install the pad pins until you hear an audible click from them. THEN re-attach the caliper to front fork, place the caliper over the brake disc with the bleeder valve facing upwards, loosely install the long caliper mounting bolt into the top hole on the fork leg, install the short mounting bolt into the bottom hole on the fork le, tighten the bottom mounting bolt to 28-38 ft-lbs (38.51.5 Nm) and final tighten the top mounting bolt also to 28-38 ft-lbs (38.51.5 Nm) and final tighten the two pad pins to 180-200 in-lbs (20.3-22.6 Nm).


THEN and whenever new pads are installed, before moving the bike pump the brakes until brake fluid pushes the caliper pistons and the pads out and verify that the pads are against the brake disc and then rotate the wheel to ensure there is not any excessive drag between the pads and the disc, check for proper fluid level in the reservoir and if necessary top it up with DOT 5 Silicone base brake fluid only, install the reservoir cover and tighten its screws to 6-8 in-lbs (0.7-0.9 Nm).


THEN and whenever any work has been done on brakes always test the brakes at low speed before operating on a roadway or at higher speeds. THEN test brake system light and if during the road test the brakes feel spongy at all bleed the system and after obtaining a hard lever or pedal road test the bike again.

how do i remove the brake caliper on a 1994 f350 4x4 there are no bolts attaching it


If this is a Pin Slider, here is 1996 steps:

Section 06-03: Brakes, Front Disc 1996 F-150, F-250, F-350 4x2, 4x4, Bronco and F-Super Duty Vehicles Workshop Manual
REMOVAL AND INSTALLATION Caliper
Heavy-Duty Rail Slider, F-Super Duty
Replace brake shoe and lining (2001) as follows when the lining is worn to a minimum thickness of 0.794mm (1/32 inch) above the front disc brake rotor shield. stj~us~en~file=ani_caut.gif~gen~ref.gif CAUTION: Always replace all brake shoes and linings on an axle. Never replace only one wheel (1007).
Removal
  1. To avoid fluid overflow when the caliper pistons are pressed into the caliper cylinder bores, siphon or dip part of the brake fluid out of the brake master cylinder reservoir (2K478). Discard the removed fluid.
  1. Raise the vehicle and install safety stands. Remove the front wheel and tire assembly.
  1. Place an appropriate size C-clamp on the disc brake caliper with end of clamp against caliper and end of screw against outer shoe. Tighten the clamp to bottom the caliper pistons in the cylinder bores. Remove the clamp. Do not use a screwdriver or similar tool to pry caliper pistons (2196) away from the front disc brake rotor (1125).




  1. Clean excess dirt from area around pin tabs.
  1. Tap upper caliper pin toward inboard side until pin tabs touch the front wheel spindle.
  1. Using Hydraulic Caliper Pin Remover D89T-2196-A or equivalent and a light hammer, drive the pin from the disc brake caliper as follows:
    1. Position the notched end of the tool against the caliper pin (retention tab half), at a 45-degree angle from the pin retention tabs.



    1. Tap the tool with the hammer to compress the retention tabs.



    1. As the retention tabs are compressed, move the tool to gain a straight approach to the caliper pin, and continue tapping to drive the caliper pin through the caliper/spindle groove.
  1. Repeat removal procedure for lower caliper pin.
  1. stj~us~en~file=ani_caut.gif~gen~ref.gif CAUTION: Do not let the disc brake caliper hang by the front brake hose (2078). The front brake hose could become stretched or twisted which can cause the front brake hose to leak and rupture, resulting in failure.
    Remove the disc brake caliper from the front disc brake rotor. If the disc brake caliper is to be removed for service, remove the front brake hose from the disc brake caliper. Plug the end of the front brake hose to prevent fluid loss and entry of air into the system. If the disc brake caliper is not to be removed, wire it up to the frame of the vehicle to avoid damage to the front brake hose.
Installation
stj~us~en~file=ani_caut.gif~gen~ref.gif CAUTION: Always replace all brake shoes and linings on an axle. Never replace only one wheel.
  1. NOTE: There is a raised section at one end of each shoe so installation can be made in one direction only.

    Install new inner and outer lining.
  1. Lubricate the knuckle upper and lower inner pad grooves and caliper grooves with Disc Brake Caliper Slide Grease, Silicone Dielectric Compound D7AZ-19A331-A or equivalent meeting Ford specification ESE-M1C171-A. Install the disc brake caliper on a front wheel spindle, making sure the mounting surfaces are free of dirt.
  1. stj~us~en~file=ani_caut.gif~gen~ref.gif CAUTION: Do not allow the tabs of the caliper pin to be tapped too far into the spindle groove. If this happens it will be necessary to tap the other end of the caliper pin until the tabs snap into place. The tabs on each end of the caliper pin must be free to catch on the spindle flanks.
    Position caliper pin with the pin retention tabs oriented adjacent to the spindle groove.
  1. Tap the caliper pin on the outboard end with a hammer. Continue tapping the caliper pin inward until the retention tabs on the sides of the caliper pin contact the spindle face. Repeat procedure for the lower caliper pin.
