What should be noted before starting work on the inspection and removal of brake discs on Mercedes-Benz 190E?

Familiarize yourself with the dangers of asbestos dust before going to work. When one of the brake disc needs a replacement, both of them should be replaced together so that they can provide proper and consistent braking with new brake pads. Start by using jack (and parking brake up supporting axle stands) to lift the front of the vehicle and put it on axle supports, and then remove the relevant front roadwheel. Spin the brake disc to examine each side; it may be better to take off the brake pads. Light scoring is normal, whilst heavy scoring or cracks means that the material requires renourishing. There can be some lip of loose rust and brake dust along the rim of the disc, which can be scraped off, but when solid material has grown up as the result of overwear, measure the disc thickness with a micrometer at various locations. When the disc is thought to be warped, look for run-out after reducing wheel bearing play as a possibility. To measure run-out, large washers under two wheel bolts are placed over the hub, connected to the hub by the disc, and the clearance between the disc and a reference point is measured during rotation of the disc. Look at the disc, checking cracks, etc., replacing as needed. To take off, loosen the bolts that fix the brake caliper mounting bracket and pull the caliper to the disc to fix it without straining the hydraulic brake hose. Take off the screw holding the brake disc to the hub and discard it because you will need another one to be refitted. When the disc is tight, tap the back of the disc with a mallet, lightly. Clean the threads of the caliper bolt hole and the disc retaining screw threads, cleaning a mating surface, and check that a mating surface is flat and clean. Install the disc into the hub, so that the pins fit correctly, and hold it in place by a new retaining screw. Insert caliper into caliper holder over disc, put in new caliper mounting bracket bolts, tighten them. Install the roadwheel again, bring down the vehicle and fit the roadwheel bolts in a tight manner. Lastly, press the brake pedal a series of times until normal pressure is restored and evaluate the braking system by working it through the paces before returning to service.

How to inspecte and replace brake discs on Mercedes-Benz C230?

Other models have cross-drilled front brake discs to cool during hard braking, although such discs can not be machined on normal brake lathes. In the case of a defected or warped disc, the direction with the lowest cost could be replacement. Start by loosening the wheel bolts, raising the vehicle, and then mounting the vehicle safely on jackstands, then remove the wheel. Secondly, before we disconnect the brake hose, we just unscrew one of the brake caliper and leave it hanging with wire to prevent undue stresses on the hose. To secure the disc against the hub, should any be necessary, reinstall some wheel bolts or examine the disc surface surface to see whether there are any light scratches, deep marks, or wide cracks, which might need replacement. Check the holes in the cross-drilled discs about the presence of brake dust, and remove it, taking care not to extend the diameter. A dial indicator must be used to inspect the disc runout, 0.003 inches or above could need cleaning or changing. Without machining the disc below the stipulated minimum thickness which is cast in the disc. To remove, clean all mounting bolts and apply thread-locking compound when mounting. Disassemble the caliper of the brake, including its mounting bracket, screw that holds on the disc, the disc, and other wheel bolts where applicable, with a mallet, as required. Rinse out the hub flange and the inside of the brake disc thoroughly using anti-seize compound to stop rust. Place the disc in the hub, screw on the retaining screw and reassemble the brake caliper and pads with all bolts tightened to the recommended value. The last thing to do is place the final part, the wheel, lower the vehicle, connect the wheel bolts, and pinch the brake pedal in place until the brakes work.

Mercedes-Benz Brake Disc

The Mercedes-Benz Brake Disc takes the energy of all the wheels and transforms it into controlled heat to provide drivers with confident and precise stopping power in city traffic or on winding roads. Celebrated around the world for combining luxury with innovative, forward-thinking technology, Mercedes-Benz combines decades of engineering heritage into vehicles that look elegant and feel dynamic, ranging from compact hatchbacks to flagship limousines, all sharing a commitment to safety, digital innovation, and energy efficiency. Its MBUX infotainment system responds to natural speech, the MB.OS platform unifies driver assist features with artificial intelligence, and constant research into battery management helps hybrids and electric models to go further and recapture energy when they decelerate. This unrelenting pursuit of progress means owners benefit from smooth performance, smart connectivity, and refined cabins that stand out in any market. Matching that brand spirit, the Brake Disc on every wheel hub, working with the caliper, converts kinetic energy into heat which is quickly dissipated through vented channels or drilled surfaces, resisting fade during repeated stops. Internal cooling vanes draw air in between the friction faces, which keeps temperatures in check, ensuring pedal feel remains firm and predictable. Whether cast in a single piece of iron for durability or bolted on to an aluminum hat to reduce unsprung weight, the disc provides balanced braking throughout the entire lineup, reinforcing the universal promise of confident control that defines the driving experience.

Familiarize yourself with the dangers of asbestos dust before going to work. When one of the brake disc needs a replacement, both of them should be replaced together so that they can provide proper and consistent braking with new brake pads. Start by using jack (and parking brake up supporting axle stands) to lift the front of the vehicle and put it on axle supports, and then remove the relevant front roadwheel. Spin the brake disc to examine each side; it may be better to take off the brake pads. Light scoring is normal, whilst heavy scoring or cracks means that the material requires renourishing. There can be some lip of loose rust and brake dust along the rim of the disc, which can be scraped off, but when solid material has grown up as the result of overwear, measure the disc thickness with a micrometer at various locations. When the disc is thought to be warped, look for run-out after reducing wheel bearing play as a possibility. To measure run-out, large washers under two wheel bolts are placed over the hub, connected to the hub by the disc, and the clearance between the disc and a reference point is measured during rotation of the disc. Look at the disc, checking cracks, etc., replacing as needed. To take off, loosen the bolts that fix the brake caliper mounting bracket and pull the caliper to the disc to fix it without straining the hydraulic brake hose. Take off the screw holding the brake disc to the hub and discard it because you will need another one to be refitted. When the disc is tight, tap the back of the disc with a mallet, lightly. Clean the threads of the caliper bolt hole and the disc retaining screw threads, cleaning a mating surface, and check that a mating surface is flat and clean. Install the disc into the hub, so that the pins fit correctly, and hold it in place by a new retaining screw. Insert caliper into caliper holder over disc, put in new caliper mounting bracket bolts, tighten them. Install the roadwheel again, bring down the vehicle and fit the roadwheel bolts in a tight manner. Lastly, press the brake pedal a series of times until normal pressure is restored and evaluate the braking system by working it through the paces before returning to service.

Q: How to inspecte and replace brake discs on Mercedes-Benz C230?
A:
Other models have cross-drilled front brake discs to cool during hard braking, although such discs can not be machined on normal brake lathes. In the case of a defected or warped disc, the direction with the lowest cost could be replacement. Start by loosening the wheel bolts, raising the vehicle, and then mounting the vehicle safely on jackstands, then remove the wheel. Secondly, before we disconnect the brake hose, we just unscrew one of the brake caliper and leave it hanging with wire to prevent undue stresses on the hose. To secure the disc against the hub, should any be necessary, reinstall some wheel bolts or examine the disc surface surface to see whether there are any light scratches, deep marks, or wide cracks, which might need replacement. Check the holes in the cross-drilled discs about the presence of brake dust, and remove it, taking care not to extend the diameter. A dial indicator must be used to inspect the disc runout, 0.003 inches or above could need cleaning or changing. Without machining the disc below the stipulated minimum thickness which is cast in the disc. To remove, clean all mounting bolts and apply thread-locking compound when mounting. Disassemble the caliper of the brake, including its mounting bracket, screw that holds on the disc, the disc, and other wheel bolts where applicable, with a mallet, as required. Rinse out the hub flange and the inside of the brake disc thoroughly using anti-seize compound to stop rust. Place the disc in the hub, screw on the retaining screw and reassemble the brake caliper and pads with all bolts tightened to the recommended value. The last thing to do is place the final part, the wheel, lower the vehicle, connect the wheel bolts, and pinch the brake pedal in place until the brakes work.
