No special tools needed. Install is very straight forward. Remove caliper bolts, remove caliper, OPEN bleed screw, press caliper into bore, CLOSE bleed screw, install new pads and reinstall caliper, top off brake fluid. You do NOT want to press the brake fluid back threw the ABS on our trucks.
I've done my front and rear pads twice as well as a buddy's, totalling aproximately 20 times that I've compressed calipers back into their bores without cracking the bleed screws and have not run into any troubles yet. I've never been aware that the bleed screw must be cracked on ABS systems! Have I simply been lucky or because I compress the caliper very slowly, I haven't messed anything up. My factory service manual makes no mention of this precaution. What risk, exactly, have I been running.
