The miller tool 8802 is outrageously priced......I got this one from princess auto in Ontario for $15.

The little nubs are 1.25" apart and the diameter of the tool is 1.5"....small enough to go through the caliper bore.....

Never ends though.....I need to buy a special socket for an oxygen sensor, had to buy an extra key fob costing over $100....and now this.....should have just bought a 2005/06 Grand Caravan LOL....what tool do I need next?

 

I did the rear brakes on our '08 T&C a couple of weeks ago. No special tools used. Both rotors were rusted on to the hub, sprayed them with PB Blaster and used a hammer to get them off. The caliper pistons have to be screwed clockwise into the bore. Yes, you can buy a special tool, or you can use needle nose pliers and a steady hand. To make it easier, I reattached the caliper by only the top bolt, swung the assembly up as high as it would go, then tightened down the bolt. Now you can use a lot of force to push the needle nose into the grooves and turn the piston. Screw the piston all the way in. If the new pads don't slide nicely in the brackets, file down the ears on the pads until they do. Sticking pads are going to drag on the rotor and wear out prematurely. I installed two new Bendix Premium PRT5844 rotors and Wagner QC1326 ceramic pads from RockAuto. The brakes feel good.

 

Needle nose indeed work if the caliper piston is not tight. Some can be impossible to turn due to rubber seals sticking too snug. I have built my own caliper tools out of thick plate with bolts threaded into it to proper depth. If you have a drill press and jig saw, it's no biggie.

However this $40 kit will do almost every vehicle on the planet.

Generally speaking, you should only retract the pistons far enough to use light force to slide the caliper back onto the new pads. It needs to be snug with light drag (near 0 clearance). If the piston is fully retracted and the caliper is "floppy loose" when reinstalled, the e-brake mechanism may go over center and cause brake malfunction. If the pads or rotors are slightly thinner than OE the brake will likely malfunction. This problem will definitely occur if the rotors or pads are used.
