brakes on 2000 wj - how to relieve pressure from ABS

Hey GUys! Simple question.

I'm reading a guide on autozone.com on doing my rotors but this is the first time doing brakes on a vehicle with ABS

step 2: Drain 2 / 3 of the brake fluid from the front reservoir. Use the bleeder screw at the front outlet port to drain the fluid. If equipped with anti-lock brakes, relieve the system pressure.

draining the fluid is not hard but how do i relieve system pressure on ABS???

thanks!

Don't need to relieve the pressure on the ABS system. I've never had to do anything different to change pads or rotors on a vehicle with ABS. Remove some fluid from the master cyl if it is full up so you have room when you push the pistons back into the caliper.

Good idea to flush/ bleed the system from all 4 wheels. Get a cheap hand vacuum pump kit and use that to pull fluid from the caliper or wheel cylinder bleeders. Don't let the resevior get too low.

Like Valkyrie said you do NOT need to relieve any pressure.

Just unscrew the resevior cap, this will allow room for extra brake fluid to collect and make it possible to press in your caliper pistions.

Once your need pads and rotors are installed, replace the resevior cap and pump the brakes until they harden. If you don't open the lines, you often don't have to bleed the brakes. If they feel soft, them bleed them.

do them as you would any other vehicle, no need to even open the reservoir if there wasn't fluid added while the pads were wearing down.
won't need to bleed them either unless you opened the lines for some stupid reason.
