Tonyrodz's Tahoe Build Thread

I need opinions--Driving home from work last night, while stopped at a light my brake pedal slowly went down lower then it should've. Driving it progressively got worse. I changed the master cylinder 2 years ago this month. Changed using an AC Delco part. Do you guys think it sound like the mc again? There's no leaks coming from anywhere, although the mc is a tad low on fluid? My question is could it be the booster instead of the mc? How to differentiate between the 2? TIA.

check your brake pads also, when the pads are thin there is more fluid in the system and the reservoir will be lower, so will the pedal feel, just kinda how it works....

I would unbolt the m/c and look at the back to see if is wet or dry. You may also have seepage elsewhere besides the back of wheels.
