Fluid: SAEJ1703 or FMVSS No.116 DOT 3 2. BLEED MASTER CYLINDER HINT: If the master cylinder has been disassembled or if the reservoir becomes empty, bleed the air from the master cylinder. (a) Disconnect the brake lines from the master cylinder. (b) Slowly depress the brake pedal and hold it. (c) Block off the outlet plugs with your fingers, and release the brake pedal. (d) Repeat (b) and (c) 3 or 4 times. 3. CONNECT VINYL TUBE TO BRAKE CALIPER BLEED- ER PLUG Insert the other end of the tube in a half–full container of brake fluid. NOTICE: Bleed air of the rear brake first. If front brake is bled first, rear brake air cannot be bled. 4. BLEED BRAKE LINE (a) Slowly depress the brake pedal several times.

Then tighten the bleeder plug. (c) Repeat this procedure until there are no more air bubbles in the fluid. Torque: (Bleeder plug) 8.3 N·m (85 kgf·cm, 74 in.·lbf) 5. REPEAT PROCEDURE FOR EACH WHEEL
R00954 Push Rod Pedal Height Stop Light Switch BR064–01 BR4980 A R00935 Pedal Freeplay BR–6 – BRAKE BRAKE PEDAL 1121 AuthorĂ: DateĂ: 1997 LEXUS ES300 (RM511U) BRAKE PEDAL ON–VEHICLE INSPECTION 1. CHECK PEDAL HEIGHT Pedal height from asphalt sheet: 152.0 – 162.0 mm (5.984 – 6.378 in.) 2. IF NECESSARY, ADJUST PEDAL HEIGHT (a) Disconnect the connector from the stop light switch. (b) Loosen the stop light switch lock nut and remove the stop light switch. (c) Loosen the push rod lock nut. (d) Adjust the pedal height by turning the pedal push rod. (e) Tighten the push rod lock nut. Torque: 25 N·m (260 kgf·cm, 19 ft·lbf) (f) Install the stop light switch and turn it until it lightly con- tacts the pedal stopper. (g) Turn the stop light switch back one turn. (h) Check the clearance (A) between the stop light switch and pedal. Clearance: 0.5 – 2.4 mm (0.020 – 0.094 in.) (i) Tighten the stop light switch lock nut. (j) Connect the connector to the stop light switch. (k) Check that the stop lights come on when the brake pedal is depressed, and go off when the brake pedal is re- leased. (l) After adjusting the pedal height, check the pedal freeplay. HINT: If clearance (A) between the stop light switch and the pedal stopper has been adjusted correctly, the pedal freeplay will meet the specifications. 3. CHECK PEDAL FREEPLAY (a) Stop the engine and depress the brake pedal several times until there is no more vacuum left in the booster. (b) Push in the pedal by hand until the resistance begins to be felt, then measure the distance. Pedal freeplay: 1 – 6 mm (0.04 – 0.24 in.)
R00934 Pedal Reserve Distance – BRAKE BRAKE PEDAL BR–7 1122 AuthorĂ: DateĂ: 1997 LEXUS ES300 (RM511U) HINT: The freeplay to the 1st resistance is due to the play between the clevis and pin. This is magnified up to 1 – 6 mm (0.04 – 0.24 in.) at the pedal. If incorrect, check the stop light switch clearance. If the clear- ance is OK, then troubleshoot the brake system.
