Specs: 99 Tacoma, 3.4 V6, Automatic, No ABS
Was working on my bed bob/dovetail when I decided that I needed to make an errand.... so I plugged my tail lights in real quick and secured them. When I went to make sure they were working, I discovered that the brake lights weren't coming on! The blinkers worked, and the red part worked when I turned the headlights on, but still no lights when depressing the brake pedal. I then tried to put the truck in drive and the shifter would not let me. (which tells me the truck doesn't think I'm even pushing the brake pedal.) so I checked fuses and all seems to check out there. I have been noticing a squishy brake pedal and less braking power these last couple of weeks, and it was even worse now, so I decided to inspect and bleed the system. Saw no leaks or damage to the brake lines and proceded to bleed the system with a vacuum pump (starting with RR, LR, BPV, RF, LF). It didn't help at all, so I thought maybe my pump wasn't effective so bled the system again, this time with a partner on the brake pedal. Brake pedal still very mushy (easily is pressed down to the floor) and can't shift out of park.
My guess is master cylinder....... What do you all think?
