As I change my pads at the track, I want to get the job done fast. So I use this.

I agree with him.

And have been using large channel locks and rag for 20+ years and hundreds of calipers and never scratched one.

open the brake reservoir cap and just push/pull the pad with your fingers/hands. I've probably swapped pads 25 times and never used any tool to press the pistons in. Just open the cap and it should be easy.

edit: for clarity, I pull one side back all the way with the pad still in there, then drop in the new pad. Then do the same for the other side. You shouldn't ever have to take the caliper off the hub with out brakes. Use the pins. Way safer and way easier. I have no idea why you all are using pliers and clamps and etc.

I have been meaning to do a video showing this for a while, but I haven't gone to the track. Unfortunately, the thing that enables me to go to the track (job) is interfering with my ability to go to the track! I ordered ceramic brake pads so maybe I'll get a video this weekend.

I use my fingers and do the same as VI, one side at a time. I don't open the reservoir cap. I change back and forth, street pads to track pads.

The front ones can be tough. Change one pad at a time. For example: press the pad on the inside in as far as possible and replace with new pad. Once the new inside pad is in compress the old pad on the outside as far as you can. The problem is if you compress the inside pad the outside pistons will then slide in making it hard to get the new one in on the other side. In other words, when you press in on one side the other side slides out. Hope this makes sense. I replace mine a dozen times a year for track days.

I have one of those, darn expensive and I never use it. It's just too big and cumbersome.

Amazon has several different versions at slightly different prices.

If the brake pads have ears on them the tool can also be used on the pads to push the pistons back far enough to get the pads out of the caliper. Then just insert the tool in the caliper and it pushes opposing pistons into the caliper.

I have been using my tool for close to 10 years now.

I have one of those as well. What's really great about it is that it has a fitting for a 1/2 impact. I just connect the same impact I used to remove the wheels and spin it one way to compress the pistons - super quick. I did grind the end off the metal rod you use for hand turning so you can remove it.
