How to Turn Cross Drilled Rotors
Cross drill rotors make it easy for gases that build up during braking to escape. The design on the components increases their surface area, which allows them to cool more quickly. It also improves contact pressure, which is important during braking. One of the most notable downsides in using cross drilled rotors is that they are more prone to cracking and also wear out brake pads more quickly. The following steps can be used to turn the components.
Step 1 - Secure the Car
Park the car in a spacious place and make sure there is enough area to work around it. Pay attention when working on the braking system so as to avoid causing accidents or suffering injuries.
Step 2 - Loosen Lug Nuts
On the wheel, locate the lug nuts and loosen them using a socket wrench and the correct sized sockets. Be carefully when turning the equipment so as not to damage or break the threads. Make a 45 degree turn on each nut and watch out not to unseat the wheel from the hub.
Step 3 - Jack Car
Locate the front jack point, which is the area behind the radiator, and secure the jack. Make sure it is firm and the car is supported properly with jack stands. With the wheel still in position, remove the lug nuts and release the wheel from the wheel hub.
Step 4 - Remove Brake Caliper
Locate the bolts that hold the caliper in position and loosen them carefully using a wrench. In most vehicles, brake calipers are found on cross drilled rotors. Use zip ties to hold the brake caliper to the coil springs. Make sure the caliper is held firmly.
Step 5 - Remove Rotor
Gently pull brake rotor from the wheel hub and place it in a safe position. There are car models where the rotor can be removed easily without having to secure brake calipers. Locate the two retaining pins and use a screw to remove them. Inspect the condition of the rotor; look out for damage, wear and tear.
If the cross drilled rotor is in a bad condition, replace it with a new one. Clean the mounting surface and components found in the area to remove grease, oil and other debris.
Step 6 - Turning Cross Drilled Rotors
Car owners are advised not to attempt to turn cross drilled rotors by themselves. The reason is that this procedure is done on a special instrument known as an NC machine. Turning cross drilled rotors is done by the equipment at a calculated position, followed by stress relieving procedures.
Take the components to a mechanic that offers the service.
Step 7 - Reinstall Cross Drilled Rotors
With the rotors turned, position them on the mounting surface and secure them using retaining pins. Reattach calipers and make sure they are well fastened with the bolts and nuts. Mount the wheel back in position and secure it using lug nuts. Make sure that all parts are well fastened before removing the jack stands.
