Look at the rotors for signs of overheating. With the amount of effort normally required to push the piston into the caliper, you may not be able to pick up a questionable caliper. Problems with calipers won’t be as obvious. Be sure to clean and lubricate all the hardware, as well as the pad bracket, to ensure a high-quality job. Mechanical problems, like frozen slider hardware or pads jammed in the brackets, will be obvious as you perform the service. It shouldn’t be difficult to find the cause of the uneven wear.
A brake that is dragging or not applying properly will not only hamper proper operation of the ABS, but it will definitely affect the quality of the brake service. If the pads aren’t worn equally, now is the time to find out why. While performing the brake service, look at the wear on the old pads as they are removed. It’s much safer to open the bleed valves and catch that dirty fluid in your bleeder bottle (see Photo 1). Only a tiny piece of grit can plug up the orifices located in the modulator. Gone are the days when you lower the fluid level in the master cylinder reservoir and push the fluid back from the caliper. It shouldn’t add much to the invoice since you already have the bleeders open.
At the very least, you should flush and bleed the system when replacing the pads.
