  Q: How to replace the front brake disc (JH5) on GMC Savana 1500?

  A: Start Brake Disc jh5 replacement by checking the brake master cylinder reservoir fluid level. Drain fluid to the middle point if reservoir liquid is above that mark. Lift the vehicle moderately then take off the wheel and tire parts. Keep a reference point when reinstalling the original Brake Disc because it must align with the Wheel Hub properly. Put down 2 large c-clamps onto caliper housing and push them against disc housing to draw all brake pistons into their home position. Secure the brake caliper with mechanic wire to protect the hydraulic brake hose during maintenance. Securely suspend the brake caliper assembly by removing its 2 bolts then placing wire under it during the removal process. To access the wheel studs remove Brake Disc retaining push nuts if needed and separate the Brake Disc screw. First place wheel nuts on the studs then hit between the studs for a perfect disc removal with a deadblow hammer. After cleaning all surfaces apply penetrating oil then add two m10 x 1.5 bolts in disc's threaded holes with regular tightening to push the disc away. To install the part use the j-42450-a (Wheel Hub Resurfacing Kit) to clean rust from the hub flange and use j-41013 (Disc Resurfacing Kit) to clean the inner Brake Disc surface. Apply the disc to its original position while monitoring that no particles reach the surfaces and install it. Secure the Brake Disc screw at 12 nm (106 lb in), put in the brake caliper and bracket. Prepare the mounting bolt threads by clearing away residual adhesive then using brake parts cleaner to clean the threads. Finish the preparation by applying threadlocker gm p/n 12345493 (Canadian P/N 10953488) onto the threads. Put on the two mounting bolts and secure them to 175 nm torque value. Put back the tire and wheel components before gently pushing the brake pedal to its middle range through several activation cycles until a solid braking effect exists. Add fresh brake fluid to the reservoir until it reaches the correct mark. The braking system needs to be run in with new Brake Pads against refreshed or new discs.
