Change front brake rotors on sebring 2001 - 2001 Chrysler Sebring

how are you bleeding them..there is a port on each one somewhere..

remove caliper and bracket. 4 bolts total. beat the rotor with a hammer. comes right off

Front brakes usually don't go 100K. You should have them checked now to avoid rotor damage.

If you opened a brake line,or bleed screw,then you will have to bleed the brakes.If not,check the calipers to see if one is not letting go of the brake rotor,if so,there is a brake hose going to the brake caliper ,that is colasped inside,and it needs to be replaced.

If they are not worn beyond tollerance they can be machined on the vehicle.
Also make sure its not tyres or wheel bearings.

remove wheel
remove brake caliper( leave the hose connected)
remove centre cap
remove split pin and lock
unscrew bearing hub nut
rotor should come off
fit new bearing races in new rotor
grease new bearings
fit inside bearing and seal
refit rotor, outer bearing,washer,nut,lock, splitpin and centre cap
(tighten nut until no play in bearing plus 1\8 of a turn)
refit caliper and wheel
bleed and test brakes before driving

sorry same as everyone else the disks need changing ,drive slower and use the gearbox to slow down ,in other words drive like you a practising to be a hearst driver for a funeral

Spongy means air present in the hydraulic system,I recommend check and recheck all of the brake system areas where air could enter(master cylinder,fittings,calipers,etc.)and bleed the entire system again.
Good luck !

Assuming you are not referring to the pulsation experienced when the anti-lock braking system engages, you should replace the rotors and the pads while you are at it. The days of turning or resurfacing rotors are over. They are cheap.

You need your brakes replaced all around.
