Apply brake pedal and note pedal feel and travel. Repeat this off/on procedure 10 times to cycle the solenoids. Depress the brake pedal with moderate pressure and turn on the ignition without starting the engine for 3 seconds. Bleed booster section of the booster/master cylinder assembly: Refer to “Pump Motor Runs Continuously” in this section.ġ5. NOTE: Turn off the ignition if the pump motor runs for more than 60 seconds. Turn on the ignition and allow the pump motor to run.
If necessary, top up to the correct level – see start of this section. Remove the reservoir cover and check the level in both front and rear sections of the reservoir. Wait two minutes for air to clear from the brake fluid in the reservoir. A noticeable change in brake pedal feel (to a hard pedal) will occur when the accumulator is completely discharged. Turn off ignition, de-pressurise the accumulator by FIRMLY applying and releasing the brake pedal up to 40 times. Repeat procedure on the outboard side nipple (or use the “Tech 1” bleeding sequence) Close the bleed nipple when fluid begins to flow without air bubbles With ignition on, apply light force to the brake pedal and slowly open the bleeder valve to allow brake fluid to flow until no air is seen in the fluid. Attach a bleeder hose to the bleed nipple on the inboard side of the master cylinder, and submerge opposite end in clean brake fluid.
Repeat steps 10 and 11 for the left hand rear calliper.ġ3. IMPORTANT: Final fluid level must be checked after depressurising unit at step 14.ġ2.

To avoid de-pressurising the accumulator at this interim stage, top up the reservoir rear chamber to a level 25mm below the full mark. Check fluid level in the reservoir rear chamber. Repeat as necessary until no air bubbles are seen at the bleeder hose.ġ1. Close bleed nipple, then release brake pedal. Allow fluid to flow for about 15 seconds. Note that the pump will run during this process. The harder the pedal is pressed, the more fluid will flow. With ignition on, lightly depress the brake pedal until fluid begins to flow from the hose. NOTE: Turn off the ignition if the pump runs for longer than 60 seconds, and refer to “Pump Runs Continuously” (see later). Turn the ignition on and allow the pump to run and pressurise the accumulator. Repeat steps 6 and 7 on the left hand front brake.ĩ. Repeat step 6 until the brake pedal feels firm at half travel and no air bubbles are observed in the bleeder hose.Ĩ. Check fluid level and top up as necessary.ħ. Attach bleeder hose to calliper nipple and submerge opposite end in clean brake fluid. If a replacement booster/master cylinder has been fitted, or if there is difficulty when trying t bleed the front master cylinder sections, ensure all air is removed from the master cylinder body by opening the brake pipe tube nuts on the master cylinder (front two only) approximately two turns, or until fluid begins to bleed Torque tighten the pipe nuts: - Front pipe (LHF brake) M13: 24 – 26 Nm (18 – 19 lbf.ft). Refit reservoir cover and diaphragm assembly.ĥ. Do not use DOT 5 silicone fluid or any fluid which has been exposed to the atmosphere for more than a brief period, or any fluid suspected of being wet, dirty or contaminated. Fill or top up both front and rear compartments using only DOT 4 brake fluid from a sealed container until levels reach the full marks.
Clean the reservoir cover and top of the reservoir before squeezing the release tabs and lifting off the cover and diaphragm assemblyĤ. A noticeable change in the brake pedal feel (to a hard pedal) will occur when the accumulator is completely discharged.ģ. De-pressurise the accumulator FIRMLY applying and releasing the brake pedal up to 40 times. If only a hydraulic part of the booster/master cylinder or pump/accumulator has been replaced, and air has not entered the brake lines, it may only be necessary to bleed at the booster/master cylinder bleed nipples.Ģ. If a Powermaster 11A booster/master cylinder assembly, or a pump/accumulator assembly has been replaced, or if air has entered (or is suspected in) the brake lines, the entire brake system including all hydraulic units must be bled at each wheel.

Other important references in this manual include JF.4 - Brake Level Checks and types of fluids to be used, plus JF.11 – Brake Discs types and relevant critical dimensions. This is applicable to all Lotus Esprit models manufactured between 19 fitted with ABS brakes. This information is provided courtesy of Lotus Cars Limited and may be found in the Service Notes (Lotus part number G082T0327J) Section JF. From experience resolving Lotus Turbo Esprit S4 brake problems, the following information is vital when bleeding the brakes.
