That was he sequence of events lastnight. Brakes on my denali had been grinding about a week. Then lastnight on the way home POP, Saw smoke from front right wheel and pedal goes to the floor. Luckily I wasnt in Heavy Traffic. Emergency Brake has never really held truck does nothing now. Have brake fluid at correct level. Any ideas on the brake pedal going to the floor issue. HAve an appointment to have it looked over wed. but dont want to get taken. Thanks!
Well, I'm sorry you neglected your breaks for even a day; let alone a week.
But whats done is done (hope you wont do it again)
My guess is, as noted above, that the pad was worn all the way down and the steel plate was riding on the rotor.. than the plate got to slim, slipped out and now your caliper is riding directly on the rotor. You are now going to have to replace to rotor, the caliper, and if your lucky that will be all.
Sounds like you are store for a long road ahead
Some real advice for you... next time your hear/feel/smell or think anything might be going wrong with your ride... try as hard as humably possible to sideline the vehicle, diagnose the problem, and fix it if needs be... as you are sure to find out, you will save more time, money and headache
Good luck man
