Reddit mentions of Park Tool Brake Piston Press

Since you said a few things, let me organize my responses.

1. Thanks for the data point, definitely what I'm looking for. Incidentally on the screwdriver trick: I used to do that, but I bought one of those Park pad spreader tools on a lark one day, & man, is it worth the cash. the beveled edge & thick body really help get the pistons spread evenly, easier than a screwdriver, especially on quad piston brakes. Worth the cash for sure.
   
   
2. are you talking about the bolts that hold the caliper body together, or the mounting bolts? If you're talking about the mounting bolts, I've done that. my problem is, I get it set so it doesn't rub, tighten down the bolts, & then if I have to take the wheel off, it will rub again when mount the wheel back up. Only way to fix it is to loosen the mounting bolts again & realign.
