• Q: How to replace the front brake disc on a 2500 Series on 2007 Cadillac Escalade?

  A: The process to replace front brake discs on a 2500 series vehicle starts with checking brake master cylinder reservoir fluid levels; remove fluid only when the level exceeds midway point. You should drain fluid to match the position of the midpoint if the level surpasses it. The first step involves lifting the vehicle for support after which you should remove tire and wheel assembly. Before putting back the primary Brake Disc it is vital to note where it connects with the hub. Use two large c-clamps of type j 42450-a to compress brake caliper pistons against the outboard Brake Pad until these pistons attain full retraction. Support the brake caliper with heavy mechanic wire in place to safeguard the hydraulic flexible hose. Brake caliper and bracket act as one piece so remove them by unfastening their 2 mounting bracket bolts. First pull the caliper and bracket apart and unscrew push nuts from the disc if they exist. You should strike each end of the hub or disc with a deadblow hammer while protecting wheel studs using wheel nuts. Use penetrating oil on the surfaces and insert two m10 x 1.5 bolts into the threaded disc holes to force the disc off by tightening the bolts. The friction surfaces of new discs should be cleaned of protective coating using denatured alcohol. Use the wheel hub resurfacing kit (J 42450-A) to clean the hub flange until no debris remains. Check the lateral runout of the disc assembly before installation to verify its compliance with specifications. Before tightening the bolts of the brake caliper and bracket assembly install threadlocker gm p/n 12345493 (similar to Canadian P/N 10953488) to the bolts then apply normal torque value at 300 n.m (221 lb ft). Reattach the tire-wheel assembly before lowering the vehicle. Following engine shut-off apply and release the brake pedal at a slow rate until complete pedal resistance is felt. The master cylinder reservoir needs to receive clean brake fluid until it reaches its specified fill mark.
