GSX-R 750 Pictures of how I changed the brake fluid (and clutch fluid) on my 1985 1986 1987 Suzuki GSX-R750 motorcycle.


But first, lets pay some bills:

  1. Should the brake fluid be black like that? Maybe it is just so low I can't see it. Either way, this is a sad state of affairs for my hottie. I love her. She does not care if she kills me. She is so hot.


  2. Every job begins with WD-40. These screws may never have been opened before.

  3. Never opened before, and left outside, in the rain, at the beach, apparently. Easy outs are really pretty easy. Unless you break off the tip of the easy out in the screw. Then it is a pain in the neck out.

  4. Brake fluid really REALLY should not be this color. It should be clear. When it gets to a light honey color, that's when it needs to be changed. When it gets like this, the owner should be changed. It's OK, baby, nobody will hurt you now.

  5. I Sucked out the majority of the fluid from the upper reservoir. No need to drag all that through the brake line. Look at that. Black Dot3 brake fluid. What will they think of next.

  6. So then I think you drain the caliper furthest away first. Both fronts are the same distance, so that does not matter. The Factory Service Manual (FSM) says to do the inboard bleeder valve first. All the calipers have two valves, inboard and outboard. They have little rubber covers on them.

  7. I attached a length of clear tubing to the valve, and put the other end of the hose in a jar to catch the fluid. I can watch the fluid come out to see when it changes color, and to make sure no bubbles are getting sucked back into the brake line.

  8. Then I filled the brake reservoir with new Dot4 brake fluid. Apparently Dot4 has a higher boiling point than Dot3 brake fluid. If the brakes get hot, the fluid does not boil, so that is good. Dot5 is not compatible with the 1985 1986 1987 GSX-R system. So sayeth the Google.

  9. Then I
    1. pumped the brake handle.
    2. opened the bleeder valve.
    3. closed the bleeder valve.
    4. IF BrakeFluid NOT = Clean, Then GOTO 1
    Repeated until clean brake fluid came through.

  10. Then I cleaned up. That brake fluid eats paint and any kind of finish. It is water soluble so cleanup with water and a rag should do. I think I missed a drop and it ate the paint away by the next day. So sad. Next time I will take off the fairings before I do this. I'm sorry, Baby. You still look hot in those fairings.

  11. Next I sold out to make 02ยข so I can fulfill my lifelong dream of owning a 1986 944 with blown head gaskets.

    But no minivans!


  12. Then I finished my beer.
