I had a prevous post that ended in no joy. Anyway this is the “joy” sequel to that, at least the bleeding portion. In summary here is what I did to get pedal pressure. This is after replacing the MC and servo. I did the pressure bleed method (no pedal pumping was needed). I used 60ml syringes purchased from Amazon for ~$8 (picture below of my configuration).
- After installing the MC and servo I connected both resevoir lines to syringes filled with brake fluid.
- I loosened the rear brake line and pressure bled the MC and rear brake section of the servo using the syringe.
- Then loosened the front brake line and pressure bled the front brake portion of the servo
- Removed the rear wheels and front two rear shocks for access to the rear bleeders (thanks Coventry). Also raised the front and remoeved the front wheels. Rear sagged a bit more with the two shocks removed.
- Loosened right rear bleeder. Was unable to pressure bleed initially but discovered an issue with the ball bearing in the bleeder hole. Seemed this was stuck. I learned this the hard way by removing the bleeder and trying to bleed it. The bearing ended up popping out. I was lucky find the bearing on the floor then placed it back in the hole. After that I was able to bleed it.
- I proceeded to bleed all the calipers using this method. I discovered you have to loosen each bleeder several turns in order, I presume, to allow for the bearing to “float” and pass fluid (slightly loose or 1 full turn did not work). This worked for me.
- I purged roughly a liter of fluid through the entire sytem (probably more than necessary). I used a clear line from my Mighty Vac and an old brake fluid container to capture the fluid.
- I connected the resevoirs to each line and filled with brake fuid.
- Pumped the pedal a few times…good brake pressure.
Anyway just some shared learning here. Yes as everyone says the rears are a pain in the arse. I am still not done putting humpty back together, but much was learned with this endevor. One thing to note if I removed all the roadblocks I encountered this could be done in a couple of hours or less.
