What tools to change brakes on 2004 Rendezvous

Possible wheel bearing. Does squeak go away when brakes are applied?

Besides regular hand tools and socket sets, the first thing you will see are the front caliper retaining bolts or screws. GM cars often used large hex key fittings to loosen those, but expect anything on the caliper bolts, a lot of variation between years and models.
Your very best tool is a repair manual for the rendezvous, with step by step instructions. They cost about 26-30 dollars.

You can use a low voltage tracker. Connect to end at brake assembly and test at box on top.

WHen you refer to the shift solenoid, are you meaning the solenoid that locks and unlocks the shift lever? If so, before you change this, check if your brake lights are working! A common fault for this solenoid to not work is either a blown fuse or failed brake light switch- the solenoid is activated by you pushing the brake pedal which sends its signal from the switch!

I hope this helps? Good luck!

I would start by checking for brake system codes. A parts store like Autozone should be able to do this for you.

You have a serious brake problem, most likely the front brakes are metal to metal, have it inspected ASAP, many brake shops and tire stores do this for free.
