How to stop newly installed brake padc from squelling?

You will need to get it cleared with a scan tool and see if it happens again. It could be an electrical fault

Whatever Brake work was done,was not done
correctly,that is obvious

If you sat & waited for an hour to have that done,
you learned the hard way

Brake service requires hours of work,lots of rust
removal & quality parts

It starts & ends with a road test

normaly squealing is caused by te pads still touching disks when moving put some copper grease on the backs of the break pads so when you take your foot of the brake the pads come off the disks hope this helps ivan

have the area inspected. Look for loose wheel bearings and for anything worn.

I don't think I'd go back to that shop.

If it is truly the belt, first try a new belt, but you may also need to replace the tensioner pulley.

I don't think the brakes are related, it may be the wear sensors, indicating that it is time to change the pads.

I meant to tell you also to check the wires to the newly installed brake light switch to see if the wiring is connected securely. Ity maybe loose in the connector also

Apply the emergency brake slightly while driving to see if the rear brakes are the issue. Other wise the rotors are warped or there is debris behind the rotor to hub surface

Your front brake rotors are warped. This can be caused by over-tightning the lug nuts or by high speed stops that overheat the brake rotors. You will have to remove the rotors and have then turned at a machine shop if possible. Install new pads when you do this as you should not use the old pads on the newly turned or replaced rotors. When installing the wheels make sure to torque the lug nuts to exactly 100 lb/ft and tighten them in a star pattern. Merry Christmas

you can get your breaks worked on

One of your other indicator bulbs are gone- it cuold be one of the small ones in the front wings
