Q: How to replace the brake pads on Chevrolet Colorado?
A: Begin the Brake Pad replacement by watching the master cylinder reservoir fluid level; no need to drain fluid if it stands at mid-range but fluid needs to be lowered to mid-range when above the mark. Lift the vehicle then disconnect the tire and wheel components. Trap the brake caliper in place with a large c-clamp touching both its backside to outboard pad while tightening until the pistons compress. Secure the brake caliper with heavy mechanic wire to shield the hydraulic brake hose when you withdraw the guide pin bolt from its lower position. Push brake caliper upward and take away both outer and inner brake pads. Replace old Brake Pad shims before you begin with new disc brake pads. Clean both the brake caliper needle and the mating surfaces. For used brake pads keep the shims and clean them with denatured alcohol until they are dry. Cover the brake caliper with mechanic wire and install new brake shims before putting in the outer Brake Pad then the inner Brake Pad. Hold up the caliper with mechanic wire during a low pivot to install it on the Brake Caliper Bracket. Fasten the lower caliper guide pin bolt by turning it to 64 nm (47 lb ft). Arrange the tire and wheel before lowering the vehicle. With the engine turned off apply the brake pedal steadily to 2/3rd depth and then let it return to its initial position. Keep pushing the brake pedal for 15 seconds during breaks to thoroughly position brake caliper pistons and pads correctly. Top the master cylinder reservoir to specification and perform break in procedure on pads and rotors.
Q: How to replace the rear disc brake pads on Chevrolet Malibu?
A: Begin by checking the level of the brake master cylinder reservoir; if the level fall between the maximum and minimum points, there is no need to take out any fluid out. Raise and support the vehicle, remove the tire and the wheel assembly. The large c-clamp compresses the caliper piston into the caliper bore, but make sure you do not exceed 1mm (0.039 in) of piston travel lest you create a compromise to the internal adjusting mechanism. After the compressing the piston, off the c-clamp, as well as the lower brake caliper guide pin bolt, while supporting the brake caliper with a heavy mechanic wire to avoid straining the hydraulic flexible brake hose. Rotate the caliper upside and pull out the brake pads and Brake Pad retainers from the brake caliper mounting bracket . Check the components of the brakes for worn and corroded components and replace the damaged parts. Inspect the Brake Caliper Piston boot for wear and replace if it appears to be worn. Twist the Brake Caliper Piston into the bore using a piston installation tool; install Brake Pad retainers and brake pads on to the mounting bracket. Put the brake caliper in the direction over the brakes and into the caliper bracket, install the brake caliper guide pin bolt and tighten it to 35 nm (26 lb ft). Replace the tire and wheel assembly, lower the vehicle and slowly press the brake pedal about 2/3 of its way, then release. With the engine off, do this. Do this for as many times as it takes to obtain a firm pedal that should properly seat the caliper pistons and brake pads. Finally, top up the brake master cylinder reservoir to the right level, apply and release the park brake lever four times, and burnish the pads and rotors.
Q: How to replace the front disc brake pads on the 2500 Series on Chevrolet Tahoe?
A: Before changing the front disc brake pads of the 2500 series, one must check the fluid in the brake master cylinder reservoir; if the fluid is above half way midpoint between the maximum - full & minimum allowable points, then remove fluid to mid point. Lift and jack up the vehicle, then take off the tire and wheel assembly. Press down on the brake caliper pistons using two large c-clamps between the caliper housing and the rear of the outboard Brake Pad until the c-clamps are as stiff as they can be. Remove the brake caliper guide pin bolts and hold it up with heavy mechanic wire to avoid the hydraulic flexible brake hose to be damaged. Remove the brake caliper from the bracket and remove the brake pads marking the wear sensor orientation, if so equipped. Remove the old Brake Pad retaining springs and check the brake caliper. Mount new Brake Pad retaining springs to caliper bracket, then install new disc brake pads, making sure that the object of the wear sensor points towards the respective direction. Reattach the brake caliper back to the bracket, install guide pin bolts, and apply 108 nm (80 lb ft) of torque. Replace the tire and wheel assembly and lower the vehicle down, and with the engine off, pedal the brakes somewhat more than half way, then let off gently. Do this until the pedal is fully firm to seat the caliper pistons and brake pads correctly. Lastly, if required, fill the brake master cylinder reservoir to correct level with clean brake fluid and burnish the brake pads and discs.
