Squeaking and grinding noise when I apply the brakes

SOURCE: Pulsing sound and feel from wheels

Ok, if the wheel bearing assembly was installed incorrectly the wheel would wobble and you would have a disconcerting feeling in the steering wheel. The rotors have to be within factory specs to be turned safely. What I would do is have the rotors checked with a micrometer and replaced.

could be a stone stuck in one of the calipers , sometimes driving in reverse can clear the stone.

SOURCE: Will turning rotors fix a warpage issue? Before a

well if they did a brake job at a shop they most likely turned the rotors, turning them if done right should fix it but, do not forget if they are to then below specifications it can cause it as well. I would check the price on new ones that is the better solution. If they are turned then they will be thinner and warp again even sooner.

Brakes & tires are best left to experts as your life depends on them. Get it fixed sooner then it won't be a big $$$$s fix.

You'll have to replace the pads and rotors....super simple!

They come off easy and the whole job is less than $100.....will cost WAAAAYYY more at a garage.

Removal & Installation

1. Disconnect the negative battery cable.
   
2. Remove 2/3 of the brake fluid from the brake reservoir using a clean syringe or equivalent.
   
3. Raise and safely support the vehicle with jackstands.
   
4. Mark the relationship of the wheel to the hub and bearing assembly.
   
5. Remove the tire and wheel assembly.
   
6. Remove the caliper and suspend it from the strut with a wire hook or suitable piece of wire. Do NOT disconnect the brake hose or allow the caliper to hang from the brake line!
   

1. Remove the rotor assembly by sliding it off the hub. If it is stuck on, use penetrating oil and tap lightly until free.
   

1. Install the brake rotor over the hub assembly.
   
2. Install the brake caliper as outlined in this section.
   
3. Install the wheel and tire assembly.
   
4. Carefully lower the vehicle. Tighten the wheel lug nuts to 100 ft. lbs. (136 Nm). If the lug nuts aren't tightened properly, the rotor will warp from heat, causing premature wear and noise.
   
5. Fill the master cylinder reservoir to the FULL level with the correct type of DOT 3 brake fluid from a clean, unsealed container.
   
6. Firmly depress the brake pedal three times before moving the vehicle.
