…for that price, buy a bunch of them. You need a decent cheater bar and some type of penetrating fluid. Also a friend is always handy when working with rusty bolts.
For those brake pistons you have to rotate to release.
Rarely do I work on a car without finding a reason to use one of these:
Got this for Christmas this year and have used it several times in the garage and around the house. Magnetic and adjustable to have light right where you want it, but small enough that it fits everywhere.
Big ass sheets of cardboard to lay on, and protect the driveway from drippage.
I don’t even know what to call them, but those long flexible grabber things that can pull dropped nuts out of hard to reach places, also works for VW enthusiasts who chew gum.
Good thing I’ve never tried to put the jack in the center of the car and lift the whole thing.
I made one when I couldn’t find mine once. Took a big fender washer, cut a square hole in the center for the ratchet, and put two small bolts through the outter edge of the washer to act as the teeth that grab the piston notches. Worked surprisingly well.
