Your brakes are vacuum aided so when engine is off the pedal will be hard. When the engine runs the vacuum is active and the pedal becomes light. Your brakes are working but need adjustment so that the pedal does not go to the floor.
Locate the adjusting screws behind the rear wheel drums.
With one wheel jacked adjust the shoes till wheel wont turn.
Then loosen until wheel is just free of any friction from shoes.
Repeat for other side.

I have a 2004 Land cruiser and changed the right rear brake cyl and brake shoes . What is the proper procedure to bleed the rear brake system. Thank you for your help.


  1. Check the fluid level in the reservoir after bleeding each wheel. Add DOT3 fluid, if necessary.
  2. If the master cylinder was disassembled or if the reservoir becomes empty, bleed the air from the master cylinder as follows:
    1. Disconnect the brake lines from the master cylinder.
    2. Slowly depress the brake pedal and hold it.
    3. Block off the outlet plug with your finger, and release the brake pedal.
    4. Repeat 3 or 4 times.

  3. Bleed the brake starting with the one furthest from the reservoir and then the next furthest, etc.
  4. Depress the brake pedal several times, then loosen the bleeder plug with the pedal held down.
  5. At the point when fluid stops coming out, tighten the bleeder plug to 11 Nm (8 ft. lbs.), then release the brake pedal.
  6. Repeat until all the air in the fluid has been bled out.
  7. Repeat the procedure to bleed the air out of brake line for each wheel.
  8. Check the fluid level and add DOT3 fluid if necessary.

well, a hard firm pedal, usually indicates a bad brake booster or a vacuum leak to booster or the vacuum check valve, on booster. TO TEST BRAKE BOOSTER; pump brakes several times with engine off to deplete stored vacuum. turn on engine with pushing slightly on pedal. you should feel the pedal fade away a bit and then become firm, but not hard. if you feel nothing at the pedal when engine starts the booster is at fault. good-luck !!

Hilux clutch master cylinder seals which way do the seal or seals face.


The seals face towards the hydraulic side. Install with the wide side of the seal towards the hydraulic line. Note: it will not bleed like a brake system. Fill the resivoir and open the slave bleeder and gravity bleed, that will get you about 90%. Then get somebody to step on the pedal while you ,now, bleed it like a brake system. Good Luck!.
