the minimum allowable level, no
brake fluid needs to be removed before proceeding.
- If the brake fluid level is higher than midway between the maximum-full
point and the minimum
allowable level, remove brake fluid to the midway point before proceeding.
- Raise and support the vehicle. Refer to Lifting and Jacking the Vehicle
.

NOTE:
- DO NOT use any air tools to remove or install the guide pin bolts.
Use
hand tools ONLY.
- Install an open end wrench to hold the caliper guide pin in line with
the brake caliper while removing or installing the caliper guide pin
bolt. DO NOT allow the open end wrench to come in contact with the
brake caliper. Allowing the open end wrench to come in contact with
the brake caliper will cause a pulsation when the brakes are applied.
- Using a backup wrench to hold the brake caliper guide pin stationary,
remove the lower brake caliper
guide pin bolt (1).
CAUTION: Support the brake caliper with heavy mechanic wire, or
equivalent,
whenever it is separated from its mount and the hydraulic flexible
brake hose is still connected. Failure to support the caliper in this
manner will cause the flexible brake hose to bear the weight of the
caliper, which may cause damage to the brake hose and in turn may
cause a brake fluid leak.
- Rotate the brake caliper upward and support with heavy mechanics wire.
