Brake Master Cylinder -- Removal

HINT:

Use the same procedure for RHD and LHD vehicles.
The procedure listed below is for LHD vehicles.

NOTICE:

Make sure to release the vacuum from the brake booster before removing the master cylinder from the brake booster.

1. DRAIN BRAKE FLUID

NOTICE:

Wash off brake fluid immediately if it comes in contact with any painted surface.

2. REMOVE AIR CLEANER CASE (for 2TR-FE RHD)

Remove the air cleaner case (LandCruiser RM00000463700IX.html).

3. REMOVE AIR CLEANER CASE ASSEMBLY (for 5L-E RHD)

Remove the air cleaner case assembly (LandCruiser RM000000FYL01SX.html).

4. REMOVE BRAKE ACTUATOR ASSEMBLY (for RHD)

Remove the brake actuator assembly (LandCruiser RM0000034UX02TX_01_0002.html).

5. DISCONNECT CLUTCH TUBE (for Manual Transmission)

Land Cruiser, Land Cruiser Prado. Grj150 Trj150,155 Kdj150,155 Lj150, Gdj150,155

Slide the clip and disconnect the clutch tube.

6. REMOVE BRAKE MASTER CYLINDER SUB-ASSEMBLY

for LHD:
1. Disconnect the connector.
2. Using a union nut wrench, disconnect the 2 brake lines from the brake master cylinder sub-assembly.
3. Remove the 2 nuts and brake master cylinder sub-assembly.
  NOTICE:
  1. The master cylinder requires careful handling. Do not allow the master cylinder to receive any impact, such as from being dropped. Do not reuse a master cylinder that has been dropped.
  2. Do not strike or pinch the master cylinder piston, and do not cause any damage to the master cylinder piston by any other means.
  3. When installing the master cylinder to the brake booster or removing the master cylinder from the brake booster, make sure that the master cylinder is kept horizontal or with its tip facing downward (the piston faces upward) to prevent the master cylinder piston from falling out.
  4. Do not allow any foreign objects to contaminate the master cylinder piston. If a foreign object gets on the piston, remove it by using a piece of cloth, and then apply an even layer of lithium soap base glycol grease around the circumference (sliding part) of the piston.
  5. Do not use any other type of grease or fluid.
  6. Be careful not to damage the brake tubes.
4. Remove the O-ring from the brake master cylinder sub-assembly.

for RHD:
1. Disconnect the connector.
2. Using a union nut wrench, disconnect the 2 brake lines from the brake master cylinder sub-assembly.
3. Remove the 2 nuts.
4. Remove the clamp and brake master cylinder from the brake booster.
5. Remove the brake master cylinder sub-assembly.
