Re: Replacing Front brakes
The front brakes on the Montana are just like most of the GM products. You will need a c clamp or other device to compress the caliper piston back in. As far as other tools you may need a torx bit to remove the caliper from the vehicle. If you compress the piston you will not need to bleed the brakes. As for the pads, the harder the pads the longer they will wear. But they will also cause the rotors to wear too. I usually opt for the pads that are the middle price. Although I do like Performance Friction Carbon Metallics. The wear well and are not hard on the rotors.
I have never worked on a Montana but there are two designs on Pontiacs. The easiest design allows for the rotors to come off after the calipers are off. The others require you to remove a mounting bracket before you can remove the rotor. The mounting bolts are extremely tight and will require either a large breaker bar or an impact wrench to remove. You will also need a torque wrench to reinstall these as they are usually torqued to 150 pounds. You will have to wait until you get it torn apart to find out what type you actually have. Good Luck.
