  Q: How to replace the front brake disc on Chevrolet Venture?

  A:

  The brake rotor replacement process begins with vehicle lifting along with support. Before continuing install the c-clamp between brake caliper body and outboard disc Brake Pad while positioning the ends against the caliper body and rear of the caliper. After using a c-clamp to push the Piston into the caliper bore you should remove the clamp so the caliper can slide from the rotor. The hydraulic flexible brake hose must receive support from heavy mechanic's wire or equivalent material to stop potential damage. Disassemble the brake caliper and caliper mounting bracket assembly from the suspension knuckle while maintaining tension free hydraulic brake flexible hose conditions. Use matchmarks to find the correct position of the brake rotor on the wheel studs before you take off the brake rotor . Use the j 42450-a wheel hub resurfacing kit and the j 41013 rotor resurfacing kit to clean all rust and contaminants from the hub/axle flange joint surfaces with the brake rotor surfaces. Check both mating surfaces for any remaining foreign matter before mounting the brake rotor precisely using matchmarks to its correct position on the hub/axle flange. Perform a lateral runout measurement on the assembled brake rotor to verify optimal system performance if you removed it during brake repairs. Implement additional adjustments when specifications show a deviation. Reinstall the brake caliper and Brake Caliper Bracket as one assembly onto the suspension knuckle then install the tire and wheel assembly and lower the vehicle before performing pad and rotor burnishing if the brake rotor received replacement or refinishing.

  Q: How to service and repair front brake discs on Chevrolet Venture?

  A:

  In order to service and repair brake rotors, take into consideration that the refinishing is not included in the general procedures of routine service of the brake system, unless the certain conditions, penetrating the brake unit, are present, such as corrosion, braking, cracks, heat spots, excessive bluing discolouration, scoring, lascivious to the brakes specification, lateral runout, flash over maximum specification, the spacing of the thickness that is beyond the maximum specification. Check each rotor for these conditions, such that they can be refinished and still be above the min. allowable thickness. If refinishing is required, clean any rust from the hub of the brake rotor using the Hub Cleaning Kit (J42450-A) and attach the brake rotor to the brake lathe using the manufacturer's guidelines with vibration dampening attachments firmly in place. With the lathe at full speed enter with the cutting tools until they touch the rotor friction surfaces and verify through the witness mark the correct mounting. Refinish the rotor according to the instructions of the lathe manufacturer and check the thickness after each cut. If the rotor has more thickness than the allowable, it must be replaced. To have non-directional finish, follow the recommended speed settings as well as apply the finish with the help of non-directional finishing tool with the aluminium oxide 120 grit sand paper or sanding block having aluminium oxide 150 grit sand paper. Clean all the surfaces of friction thoroughly with a clean denatured alcohol or a brake cleaner of comparable type before taking off the rotor from the lathe. Lastly, if needed, apply the Rotor/Drum Flange Resurfacing Kit (J41013) to remove any corrosion from the wheel bearing flange to prevent excessive side runout and brake system pulsation if not done.
