So Ive done a lot of brakes, but this is the first time Ive experienced this one.
Had a OE MC fail, got my hands on one of the NEW 17mm units, Replaced F. calipers with rebuilt, + all the soft lines, the MC & the (Blue) res. line sections. All went as expected. No drama just the typical PITA installing the MC. Went about bleeding & got the pedal to near the point I thought I was done when testing a full pressure hold ...the pedal travel "breaks" & continues to the floor. (IMG:style_emoticons/default/headbang.gif) I think Ive got a leak but inspection shows its all still dry... (IMG:style_emoticons/default/blink.gif) Can a MC fail internally? Anyone witha BTDT? |

QUOTE(Ninja @ Jul 11 2026, 04:51 PM)  pressure/fails/drops to floorboard a few times. See if master fluid level stays the same. If so, they only thing can it can be doing is internal bypass in the master. Bad master! Help me out the plunger circuit is a Aluminum piece with a pair of wiper seals, behind it is a pretty beefy spring? What fails, the spring? |
