I have rebuilt my rear master cylinder with new banjo bolts, washers, seal kit, connector kit. I have rebuilt the rear calipers with new pistons, seals, banjo bolts, and nipple.
I cannot build pressure. I took everything apart again, and all the lines were clear and installed properly. All seals are installed properly. The 2 holes on the master cylinder that connect to the reservoir are clear. I have tried various adjustments with brake lever height.
I tried a combination of bleeding from master cylinder banjo bolt, caliper banjo bolt, and nipple; nothing draws the fluid.
When I remove the banjo bolt from master cylinder and press on brake foot lever, the fluid rises then immediately falls as I release foot lever. Is the fluid supposed to fall again? Shouldn't it only go in one direction? How would pressure build?
My next move is to reverse bleed by pushing fluid up from the caliper nipple with a syringe, but I don't want to waste my time if master cylinder isn't functioning properly.
Thank you for suggestions.
