  Q: How to replace the front brake disc on Cadillac SRX?

  A:

  The first step to replace the front Brake Disc starts with lifting and supporting the vehicle. Install heavy mechanic wire to hang the brake caliper during disc replacement to safeguard the hydraulic flexible brake hose. Take off the caliper assembly with bracket from the knuckle keeping the hose tension-free. Beginning with disc matchmarks against wheel studs, use a hex key to remove both the Brake Disc screw and Brake Disc unit. Clean the hub/axle flange with j 42450-a wheel hub resurfacing kit alongside the Brake Disc requiring j 41013 rotor resurfacing kit. The mating surfaces should be free from contaminants before installing the Brake Disc onto the hub/axle flange according to the alignment mark. Secure the Brake Disc mounting screw with a torque of 14 n.m (124 lb in). Measure the lateral runout of the Brake Disc assembly for proper braking performance if this procedure applies. The lro measurement needs adjustments when it passes beyond specifications. Place back the brake caliper and bracket assembly onto the suspension knuckle afterwards reinstall the tire and wheel assembly. Complete the procedure by lowering the vehicle after pad and disc burnishing becomes necessary if the Brake Disc received refinishing or replacement.

  Q: What Tools Are Required to Service and Repair the Brake Disc, and What Considerations Should Be Taken into Account Regarding Refinishing on Cadillac SRX?

  A:

  Performing brake disc services needs both Rotor Resurfacing Kit (J 41013) and Wheel Hub Resurfacing Kit (J 42450-A). The brake system service on disc brake discs usually does not need disc refinishing and new discs should remain untouched with this service. Refinishing works when the disc maintains its thickness and shows signs of serious thickness problems plus corrosion, pitting, cracks, heat spots, discoloration from discoloration, and marks that go beyond official specifications. Before working on the pieces clean rust and contaminants from the brake disc and hub/axle joint using Wheel Hub Resurfacing Kit (J 42450-A) and Rotor Resurfacing Kit (J 41013). Apply the brake disc to the lathe as the maker suggests while checking both mating surfaces for unwanted particles. Start the lathe machine and let your cutting tools touch the brake disc surfaces to see the feedback mark showing correct assembly. Mount and refinish the disc through the lathe steps as the manufacturer suggests while regularly measuring machine thickness. A disc replacement is necessary when refinishing shows the part has gone above its permitted limit. Set the recommended speed and sand with 120 grit aluminum oxide non-directional tool if available or use 150 grit aluminum oxide block for non-directional finish. Use denatured alcohol or brake cleaner to clean the contact areas and then measure assembled LRO alignment on the disc to perfect brake operation before replacing the disc.
