Fixed brake lights...brake pedal is now super stiff...

[kamechikara]

Hey guys

My brake lights were stuck on so I replaced the little nub that touches the brake pedal sensor. The lights now go off but when replacing the nub, I had to press the pedal a bunch of times making it very stiff (with the car turned off). Once I turned the car on and went for a drive, the brake pedal is still really stiff. I can still brake but the brakes are always partly engaged and the pedal will not relax to a normal feel. Before this the brakes worked fine (Q45 fronts). I am considering the vacuum line to the booster...and also the booster length setting (take off the master cylinder and adjust the length). When looking over the vacuum line for leaks, how can I be sure if there is a leak or not without just replacing the hose? Any other ideas about how to get the pressure in the pedal to release?? Any help of suggestions would be appreciated. Thanks a lot!

I checked the check valve on the vacuum line and it is facing the correct way and does not leak. Also checked the vacuum lines themselves and they seem pretty sounds/leak free...any ideas on what could cause this pedal stiffness? It remains stiff (brakes are partly engaged) but functional when the car is on and off.

Anyone got any ideas? Brakes peadl is still extra still and won't relax so I have not been able to drive yet....I took off the vacuum line to see if it made any difference...it did not. I am thinking of bleeding the lines to see if that lets the pressure out.

re-bleed the brakes to start off with since it's the cheapest option.

Bled the brakes and now they are cool. Thanks for that. The lights still stay on though! Even though I replaced the sensor tab...wtf this is dumb...I might just unplug my tail lights lol
