Brake System
CAUTION:
DO NOT allow reservoir to run dry during brake bleeding procedure. Immediately clean surface if brake fluid is spilled, as it will damage painted surfaces. Use only DOT 3 brake fluid. DO NOT mix fluid with any other types.
- If master cylinder is rebuilt or reservoir is empty, bleed master cylinder first. Bleed wheels in sequence. Start on wheel with longest hydraulic line, and work toward wheel with shortest hydraulic line. See BRAKE LINE BLEEDING SEQUENCE table.BRAKE LINE BLEEDING SEQUENCE
Application Sequence LS400 RR, LR, RF & LF - Raise and support vehicle. Ensure brake fluid reservoir is at least half full during bleeding procedure. Connect one end of transparent vinyl tube to bleeder plug. Submerge other end of tube in a container half filled with clean brake fluid.
- Have an assistant depress brake pedal several times and hold in depressed position. Loosen bleeder plug, and drain fluid into container. Tighten bleeder plug.NOTE: Ensure brake pedal remains depressed until bleeder plug is tightened.
- Refill brake fluid reservoir if necessary. Repeat step 2) until air is no longer discharged. Tighten bleeder plug to 97 INCH lbs. (11 N.m). Ensure fluid leakage is not present. Add fluid to reservoir. Repeat procedure for remaining wheels.
