1. The first time was because my pedal pushrod was not properly adjusted. It didn’t have free play before contacting the master cylinder plunger, so the MC plunger was not able to fully return. If I cracked open the bleeder I’d get a squirt of brake fluid and the problem went away for a little while until I made a dozen or more stops.
2. The second time was because the new brake booster intermediate rod was not properly adjusted. So it was not allowing the MC plunger to fully return. This one was hard to diagnose because I was 100% certain my pedal pushrod was properly adjusted with the right amount of free play.
3. As others have mentioned, you could have a collapsed brake hose somewhere.
4. Dirt in the MC passages could cause this problem but less likely that the first 3. | | |
