Rear brakes (driver-side) squeal after replacing rotors and pads
I just replaced the rotors and pads on the front and rear of my 2006 hyundai tuscon....the back driver side squeals all the time while driving. What could be the problem. I replaced the rear rotors and pads first, then still noticed a squealing, so I thought I might as well do the front....still getting a squeal fron the rear driver side all the time while driving. Do I need to put anti-squeak compound on the pads? I noticed that the new rotors are not all shiny. Only about half of the rotor (inside) is shiny, the outer part orf new rotor is rusty....bad pads ?

Re: rear brakes (driver-side) squeal after replacing...
You need to grease the metal clips at the top and bottom of the pads (dont get grease on the rotor or pad though) and also spray some "disc brake quiet" on the back of the pads. it comes in a red can and the spray that comes out is like sticky red paint. do those 2 things and the squeals will be gone.

Try re-bleeding ALL wheels starting with furthest away - pass rear, then driv rear, then pass front and driv front. That should get your pedal back. To reset light you need ABS reset tool and it's EXPENSIVE. Have a good competent shop reset it for you. Body shops can reset them also.
Before servicing the vehicle, refer to the precautions in the beginning of this section.
Remove or disconnect the following:
Clip, 2 caliper pins, the anti-rattle spring then remove the 2 brake pads and the 4 anti-squeal shims
CAUTION Only replace brake pads on 1 side of the vehicle at a time. Failure to use this procedure could cause the caliper pistons on the opposite side of the vehicle to pop out requiring the reconditioning or replacement of the brake caliper.
Remove a small amount of brake fluid from the master cylinder.
Install a used brake pad into the caliper and compress the caliper pistons.
Apply disc brake grease to both sides of the inner anti-squeal shims.
Install or connect the following:
Anti-squeal shims to the new brake pads NOTE: When replacing worn pads, the anti-squeal shims must be replaced together with the pads.
2 brake pads
Anti-rattle spring and the 2 caliper pins
Depress the brake pedal several times to seat the brake pads.
Check the brake fluid level and top off as needed.
sounds like the pads have worn down, or there's debris between the pads & rotor. in my personal experience, the stock rotors from hyundai don't hold up very well. i replaced pads (front and rear) at around 45K miles, and had the stock rotors turned down. less than 1K miles later, the front rotors were already warped! there have been many complaints about hyundai's rotors, so i replaced mine with a set of raybestos rotors and also put ceramic pads up front. 20K miles later, they're still working great.
You, Probably will, Brake Squeal is NOT a new problem.
Disc brake's have been Squealing since, They, became
factory installed on chevrolet in 1971. Before, that they,
were a option. In 72 they even had a bulleton how, to
FIX it. And, no it didn't work.
With That said, Any time you replace Brake pads you,
should always re-surface the Rotors.
Why? First you may start to notice a pulsation as the
pads ware (sometimes! ) The best way to avoid, brake
squeal is to manchine the Rotors put, the blue membrain
sealent on the back side of the pads. And hope that works!!
Some brakes Pads squeal JUST SQUEAL??
You, Could do the same Brake job the same as you did
this one and, they may NOT Squeal.WHY, I WISH I NEW. They
sell all types of STUFF to stop Brake noice DON'T waste your $$.
This sounds like a wear indicator( a metal tab on the brake pad) is doing its job, warning you that the brake pads need replacement soon. you can bend the wear indicators away from the rotor so they won't make contact. This will stop the annoying noise. Replace the pads and check the brakes soon. Brake pads should always be changed on both wheels at thge same time, so change the other front pads also.
Did you buy factory pads or get cheap aftermarket pads? If aftermarket did you get the ceramic? The cheap aftermarket ones tend to squeal pretty bad. Like the last comment on here, you should have your rotors turned whenever you change the pads.
