Downloaded from www.Manualslib.com manuals search engine NOTE :
Never allow the brake master cylinder to empty of brake fluid while bleeding the brake system.
Attach a clear plastic hose to the bleeder screw and
feed the hose into a clear jar containing enough fresh
brake fluid to submerge the end of the hose.
1. Turn the ignition switch off.
2. Have a helper pump the brake pedal three or four times and hold it in the down position.
3. With the pedal in the down position, open the bleeder screw at least one full turn.
4. Once the brake pedal has dropped, close the bleeder screw. After the bleeder screw is closed, release thebrake pedal.
5. Repeat the above steps until all trapped air is removed from that wheel circuit (usually four or five times).
6. Bleed the remaining wheel circuits in the same manner until all air is removed from the brake system. Monitor the fluid level in the master cylinder reservoir to make sure it does not go dry.
7. Check and adjust brake fluid level to the MAXmark.
8. Check the brake pedal travel. If pedal travel is excessive or has not been improved, some air may still be trapped in the system. Re-bleed the brakes as necessary.
9. Test drive the vehicle to verify the brakes are operating properly and pedal feel is correct.
Pressure Brake Bleeding
NOTE :
Follow pressure bleeder manufacturer’s instructions for use of pressure bleeding equipment.
Fill the brake master cylinder reservoir to the proper level with brake fluid.
Attach the pressure bleeding equipment to the master cylinder.
NOTE :
Never allow the brake master cylinder to empty of brake fluid while bleeding the brake system.
Attach a clear plastic hose to the bleeder screw and
feed the hose into a clear jar containing enough fresh
brake fluid to submerge the end of the hose.
1. Turn the ignition switch off.
2. Open the bleeder screw at least one full turn or more to obtain a steady stream of brake fluid.
3. After approximately 120-240 ml of fluid has been bled through the brake circuit and an air-free flow is main- tained in the clear plastic hose and jar, close the bleeder screw.
4. Repeat this procedure at all the remaining bleeder screws.
5. Check and adjust brake fluid level to the MAXmark on the reservoir.

Master Cylinder - LHD
Description
The master cylinder body is an anodized aluminum casting. It is located at the left side of the engine room. It has a
machined bore to accept the master cylinder pistons and also has threaded ports with seats for hydraulic brake tube
connections. The master cylinder has the brake fluid reservoir mounted on top of it and supplies brake fluid to the
master cylinder as required. On manual transaxle equipped vehicles, the brake fluid reservoir also feeds the clutch
hydraulic circuit. The reservoir is made of clear plastic and it houses the brake fluid level switch.
Operation
When the brake pedal is pressed, the master cylinder pistons apply brake pressure through the chassis brake tubes
to each brake assembly. The brake fluid reservoir supplies the brake hydraulic system with the necessary fluid to
operate properly.
Removal & Installation
CAUTION:
The vacuum in the power brake booster must be pumped down before removing the master cyl-
inder to avoid damaging the master cylinder and to prevent the booster from sucking in any con-
tamination. This can be done by pumping the brake pedal while the engine is not running until a
firm brake pedal is achieved.
1. Turn the ignition switch off.
2. Siphon out as much brake fluid as possible from the master cylinder.
3. With the engine off, pump the brake pedal 4-5 strokes until the pedal feel is firm.
4. Disconnect the negative battery cable.
5. Disconnect the brake fluid level switch electrical connector in the master cylinder brake fluid reservoir.
6. Disconnect the brake tubes (1) at the master cylin- der outlet ports. Install plugs at all of the open
brake tube outlets on the master cylinder.
(Tighten: Brake tube nuts to 10 N·m)
