Q: 2012 Chevy Equinox brakes pedal goes to floor then works tightly

asked by on August 07, 2017

My wife's SUV suddenly suddenly won't stop when you press brakes. The pedal will go all Tyne way to the floor and feels squishy. If you let off and press again it grips tightly and will lock up. I checked the fluid andis halfway full.

My car has 128000 miles.
My car has an automatic transmission.

The master cylinder not holding or getting pressure the first time is a bad residual valve built into the master cylinder. You will need to replace the master cylinder and bleed the system air out.
