1995 Chevy Silverado V8 Four Wheel Drive Automatic 164000 miles
I have had to replace the master cylinder on my 1995 cheverolet truck 3 times in the last 2years. Each time the antilock brakes kicked in due to wet rough roads and after the brake pedal goes all the way to the floor. Ireplaced the master cylinder being very careful to bench bleed it but I still got air in the system and had a terrible time bleeding the system. I wondered if the ABS could be blowing the seals of the master cylinder.
