Up next is pressing in ECS Tuning (forum sponsor) brass caliper slide kit.
Unlike other kits, this one comes with stainless steel caliper pins so they won't corrode and seize the pads, has rubber O-ring at the ends of the brass so it keeps the lube in and debris out, and I bought it with install tool kit so there's little chance for the brass or aluminum calipers to get damaged. Install is done using hand tools.
I will be putting them on rebuilt calipers so there's no need to clean the holes the brass guides will go in. If there's rust, etc. they can deform the brass guides enough to not let the caliper pins slide.
One thing I would change from their manual is to put the lube IN the brass guides.
If you put the lube on the pins like the instructions say, the O-ring at the opening of the brass guides will just wipe them out!
