You need to take off the tire and using a prybar or large screw driver, force the caliper open by prying in the brake pad through the opening on the ccailper. One you get some slack in it, there are two bolts or screws in the ears of the caliper that must be removed. They may be an allen wrench style or a torx style. Not the bolts that hold the caliper bracket to the hub. Caliper should be able to be removed now. You then need a "C" clamp or caliper pistor compressor to push the piston all the way into the caliper in order to make room for the new pads. Good luck.

    Thanks! witserv,
    I replaced worn pads. Excellent instructions, by the way.
    ABS light still continuously blinks though. How would I determine if there is a faulty speed sensor as the culprit or accumulator, possibly?

    Sounds like a bad hub. Newer cars now have sealed front hubs with an internal speed sensor. I would do this to check. Lift the tire off the ground, and using your hands grab the tire tread at the 12 and 6 oclock position. see if there is any movement by pushing in with your top hand and out with your bottom hand. Try again at 3 and 9 oclock. If you detect any movement also check other suspension components (ball joints, tie rod ends, etc). May also spin the tire to see if you feel any friction or grinding (not associated with the pads rubbing on the disk. You can also tell a hub is going bad when you hear a rumbling from the tire that is not normal. And sometimes the speed sensor in the hub goes bad alone. Search the internet from rock auto or others for the better pricing on hubs. Install is basically undoing everything you did with the brakes, remocing the caliper support bracket, and in your case front drive nut, hub mounting bolts and pull the hub off. Good luck!

    Thanks! johnnyrobin,
    I replaced worn pads but ABS light still continuously blinks. Wondering if possible air bubble in line or speed sensor could be at fault?

Remving caliper pins on 2000 vw jetta and caliper

For front brake pads replacement you need only usually wrench set, inclusive 7 mm allen key also. But for rear brake pads replacement you need obligatory a special caliper piston pressing tool, in order to press back rear caliper piston with parking brake automatic adjustment!!!
For front brake pads. You should buy the brake pads (with wear sensor). For change front brake pads you must raise vehicle, remove wheels, extract the retaining spring of the caliper, and remove the caliper as follow:
1. Do not disconnect the brake hose from the caliper, and do not allow the caliper to hang by the brake hose!
2. Remove top and bottom caps (on back side of the caliper) for access to guide pins, then unbolt and remove them from the brake carrier. Remove the caliper.
3. Now you must thoroughly clean the brake calipers (free of grease).
4. Remove outer brake pad from brake carrier.
5. Pull inner brake pad out of brake caliper piston.
6. Check up the brake fluid level on the reservor, and emptying if neccessary!
7. Push piston back into brake caliper housing.
8. Install inner brake pad (with expanding spring) in brake caliper piston. (Arrow marked on pad - if exist, must point in direction of brake disc rotation when vehicle is moving forward).
9. Install outer brake pad into brake carrier.
10. Bolt brake caliper housing to brake carrier using two guide pins. Tightening torque is 25 Nm.
11. Install both caps.
