9 Brake

9.1 Brake Fluid

Brake fluid will damage paint.

  • use DOT-3

Brake should be bled whenever a brake line is disconnected.

  • If the disconnection is master cylinder, Start at the brake caliper or wheel cylinder farthest from the brake master cylinder, and move to the next farthest.
  • If not master cylinder, start from the closest to the disconnection point.

9.1.1 Brake fluid air bleeding

  • jack up vehicle
  • remove bleeder cap, attach a vinyl tube to the bleeder screw
  • place the other end of tube to a brake fluid-filled container
  • the first person depress the brake pedal several times, then hold it in depressed position
  • the second person loosen the bleeder screw, drain out the fluid and closes the screw
  • repeat the first-second person steps until no air bubbles. The reservoir should be kept about 3/4 full during the process.
  • tightening torque (8mm): 5.9-8.8 N.m

9.1.2 brake fluid replacement

There is no such instruction in the manual. However, searching the internet gives me a rough idea

  • suck all the fluid in the reservoir with a turkey baster
  • wipe it
  • add new fluid
  • air bleeding

9.2 Disk

  • front disk pad thickness 1.0mm min. look through the caliper inspection hole and verify the remaining thickness of the pad.
  • front disk plate thickness 18.0mm min
  • rear disk pad thickness 1.0mm min
  • rear disk plate thickness 8.0mm min

10 Clutch

If any clutch pipe has been disconnected, add brake fluid and bleed the clutch.

  • use DOT-3
  • bleeder screw tightening torque: 5.9-8.8 N.m
  • clutch fluid replacement
    • drain the fluid from the reservoir
    • remove bleeder cap from the clutch release cylinder and attach a vinyl hose to the bleeder screw
    • insert the other end of the vinyl hose into a clear container
    • loosen the bleeder screw
    • with another person slowly pumping the clutch pedal, drain the fluid from the clutch system, repeat until all fluid is drained
    • tighten the bleeder screw
    • fill the reservoir to MAX
    • bleed the air from the clutch
  • clutch fluid air bleeding
    • remove bleeder cap from the clutch release cylinder and attach a vinyl hose to the bleeder screw
    • place the other end to a clear container
    • pump clutch pedal several times
    • with the clutch pedal depressed, loosen the bleeder screw, then close it.
    • repeat last two steps until clean fluid is seen
    • tighten the bleeder screw.

11 Transmission

  • check
    • remove check plug at the driver side of the transmission
    • verify that the oil is at the brim of the check plug hole
    • apply sealant and install
  • check plug (24mm?) tightening torque: 25-39 N.m
  • drain plug (22mm?) tightening torque: 40-58 N.m
  • Transmission Oil Replacement
    • remove drain plug and check plug
    • drain the oil
    • install drain plug with new washer
    • add oil to check plug hole to the brim
    • apply sealant to check plug and install
  • shift lever turret
    • pump out the old fluid and fill in the new one. use the same oil as transmission fluid. Capacity: 80-95cc.
    • apply grease to the shift lever component
    • apply sealant to the contact surfaces of the shift lever component and the change control case.
  • other references
  • replace every 48 month or 60,000 miles
  • use SAE 75W-90 GL-4, 2.1 quats

12 Power Steering

If any power steering fluid line has been disconnected, add ATF M-III or equivalent (e.g. Dexron II), bleed the fluid line.

  • Air Bleeding
    • inspect fluid level
    • turn the steering wheel fully to the left and right several times with the engine not running
    • inspect fluid level. If it has dropped, add fluid
    • repeat steps 2 to 3 until the fluid level stablizes.
    • start the engine and let it idle
    • turn the steering wheel fully to the left and right several times
    • verify that the fluid is not foamy and that the fluid level has not dropped.
    • repeat last two steps
  • There is no section for flush it. I think
    • from the reservoir, pump out old fluid as much as I can
    • add new ones
    • do air bleeding
