What does the caliper boot do?
“Pin Boots” are small tubular, ribbed rubber components (red in the picture) that snap into grooves in the slide pin and also the fixed caliper bracket. Their job is to keep the water, sand and dirt away from the slide pin bores and helps keep the special grease inside.
What happens if your caliper is torn open?
If the caliper boot is torn open then you will get dirt, debris, water, and road salts in the caliper piston surface. The caliper may seize or tear the caliper piston seal causing a loss of brake fluid.
Is it safe to drive with a torn brake caliper boot?
Loosing pressure and fluid in the brakes could cause a dangerous situation on the road. If you’d like to get this repaired at your home or office, I recommend having brake caliper assembly replaced by one of our mobile technicians.

What to do if your front caliper dust boot is torn?
I’d have probably replaced both calipers if I discovered the boot on one was torn as part of doing the brake job. Bleeding the ABS varies car to car. It’s usually best to do it with the aid of the factory scan tool so the solenoids can be cycled as the bleeding is being done.
What should I do if my brake caliper cracks?
Keep your hands clear. The piston will come out. If the piston won’t come out easily, work it out with your fingers, and you’ll see the dust boot. You need to remove the dust seal and the piston from the bore, and for this you should use something non-metallic. Once the bore is clear, use brake cleaner or denatured alcohol to clean it out.
