Will compressing caliper damage ABS?
Hey, guys,
I remember a mechanic in the late 1990s telling me that he commonly saw jobs where people had tried to compress calipers on vehicles that had ABS without properly preparing the system, and he said that doing this ruined the ABS system and cost like $1500 to replace whatever got ruined in the process.
I need to do brakes on my 2001 F-250 with ABS (4-wheel disk brakes) ... do I need to do anything special before compressing the calipers with a clamp?
Thanks in advance.

Not unless you classify taking the cap off the master rez like DD posted above as special.
Compress without any worrys about the ABS.

Thanks, fellas.
Dumb question, probably, but since I'm replacing the rotors and pads and a brake line that sprung a leak – and probably a bunch of other stuff, the underside of this truck looks like it was on the bottom of the Dead Sea for 600 years – I'll probably have plenty more dumb questions!

Was thinking about your quest and see your a new user.
Make damn sure you use your old pad and compress both cylinders equally.
IOW: Twin caliper pistons..........see where I'm going. Make sure your bleeder is already open. If you compress 1 at a time, you'll pop the other cylinder on the caliper. If so, the pooch is screwed.
Heads up brother.

And don't press the brake pedal if the reservoir is empty, you will get air in the ABS unit then you will need a scanner capable of opening the ABS solenoids to bleed the air out.

The ABS sensor is on the bearing hub and not connected to the brake caliper assembly in any sort of way.
I'd replace the brake lines on all wheels, since your truck is 16 years old... like mine...
Do as everyone has said above... you'll be fine
