My brakes that get stiff the more I drive. After about 10-15 min. Also check my brake pads my front left is worn out and the front right is in good condition?

It could be something in your steering column or worn wheel bearings.

did you blead the brakes when you got done changing them? if not than ther might be air in the lines making it when you press the brakes it applies the pressure to the left side front first and then ttoo the right....... if there is air in the lines it will grab the front drivers side first because it is the caliber closest to the brake booster.

The brake lining's have worn away, the squealing was metal to metal (worn pad against metal disc) The worn pad will have damaged the brake disc. Very dangerous. You will now have to have new brake pads and discs fitted to BOTH front wheels to put it right. Good luck

Can you say for sure that the pull is not from a worn steering part ?
If the steering is tight, it could be a situation where the right side is not working as well as the left. Not as much pressure being applied to the pads.
Its possible there is something going on with the equalizer valve.

This symbol is for worn brake pads. When the pads wear down the sensors make electrical contact with the disc rotor and the light comes on as the circuit is completed. Check out brake pads all round, inmost cases the pads at the front wear down first. Check symmetry of wear. The pads should wear symmetrically and evenly either side of the brake disc. If the pads are wearing on just one side of the disc check that the caliper body is not seized and that the brake guide pins are allowing freedom of movement. It is always a good idea to replace all the pads on one axle at the same time as this ensures even braking. Remember, after replacing pads to pump the brake pedal until stiff prior to moving off so that you can be sure that you can stop when you have to.

get your car to a service centre immediately, squeaking usually indicates worn brake pads, most brake pads now have things called shims, that let out an almighty strange squealing sound that goes on and off as the wheel turns, as you get faster, it gets quicker, it might be front brakes or rear brakes, but make sure you get them all checked, i have had on more than one occasion, front left brake pads ok, front right low, or rear and vice-versa

Sounds like the pads are completely worn or either crystallized. The crystallized happens when the brakes get hot and cool water hits them, this will also warp the rotors. With the brakes pulsating, it may be the rotors are warped and have worn the brake pads uneven. I would have the rotors checked when buying new pads and if they are warped, buy new ones. If their not warped to bad, sometimes these can be machined until even but you never know how much metal will be left on the rotor.

Check your brake pads for wear. If worn replace. If not check the wires to the pads. If these wires are broken...the light will illuminate although the brake pads may be fine
Good luck with it

have your brakes checked. depending on your driving habits , brake pads can wear out as little as 20,000 miles

brakes or wheel bearings, a shop should be able to diagnose one or the other, maybe both.
