Need pointers/help
My car has about 36k miles on it and I don't drive it terribly hard, I do sometimes. Near the right rear wheel there seems to be a squeeking sound coming when I mash the brakes and while I'm driving I can hear it too. I used up a bottle of brake cleaner on all 4 wheels, mainly the right rear. The brakes feel fine and the car stops fairly well. If I do find that I need to get new brakes and rotors what are a good set of brakes and rotors that yall would recommend. I am open to drilled and slotted rotors if I'm going to hae to change the mout. Thanks.

We need a little more info...
Is it a constant squeaking while you are moving, or does it come and go depending on what you are doing with the car, ie...braking, cornering ect...
Peace

It starts as soon as the wheels start turning and it makes the squeek per revolution so it is not a contiunous sound. It also reacts to when I hit the brake. It sounds like there may be debri on the pad and it is grinding on the rotor or something like that, but it is definitely in the brakes unless the rear end is making the noise but I really doubt it.

Start with the easy...
Take off your RR Wheel
1) Check your caliper and pads
2) check your E-Brake.
3) wheel bearing
4) Shock and sway busings

GM stock brakes have a tell tale that causes a chirp/squeak when the pad life is nearing its end.
This alerts you to change the pads before you grind the rotor...
Generally when you load/unolad the brakes, the chirping stops
BUT you rear brakes should last longer than 36K.
You also could have a small stone stuck stuck between the pad and rotor
The brakes could be "glazed" from localized overheating from too much riding the brake
You also could have too hard a pad compound. Harder pads( that stop more quickly like some Auto-X pads ( ferro carbon Hawk HPS, HP Plus)
You really need to take off the wheel and see what is going on...
It might alos be a bad wheel bearing.. with the rear corner lifted yank on the tire at 3 & 9 o'clock and again at 6& 12.... Is the wheel tight or is it wobbly... If there is too much movement its the wheel bearing
