I have a 2006 chevy malibu and I just put new brakes and rotors on the front. when you drive the car for a little while and it is warm out the brake peal gets hard and from then on the car shakes bad
It shakes bad till it cools down and then once it warms up the brake pedal gets
hard and the car shakes bad untill it sets for a while
Lift the front end and check to see if the calipers are locked up. Spin the wheels, should spin freely.
what would cause them to lock up
The caliper pistons get dirt around the piston and so when you collapse it the dirt gets along side of the wall, or just corrosion inside around the caliper piston, or the brake line hose running to the caliper can go bad internally not allowing the fluid to flow, keeping pressure on the caliper piston. Two other things to cause a caliper to be locked up would be the slide pins being frozen up, or if the master cylinder reservoir is over full with brake fluid. The fluid level should only be up to the fill line.
