To "turn" a rotor means to put it on a laith and "make it true." This is done with a special carbide cutting edge which slowly moves across the turning disk. This gives you a nice flat surface again. Cost? about $25 per rotor. Volvo now recommends new rotors if the old ones are not smooth. This is ok if you don't mind spending the $70, but one can "turn" old rotors two or three times before you need to replace them. p.s.

You can "float" your stock rotors if they're slightly warped, or if you just like the jingle bells sound they make. Use the ball end of a brake lever and a socket a little bigger than the back end of the buttons on the rotor. Put the ball end on one side, the socket on the other, and squeeze the whole contraption in a vice. Repeat equally with all the buttons, and your rotors will dangle in place.

Vented brake disks are hollow on the inside. They look like a sandwich and allow air go inside of them, therefore cooling them off. Remember, the cooler your brakes are, the better braking performance you get. See similar questions...

The U.S. market was denied the more efficient two-piece rotors offered in the rest of the world because BMW of North America was concerned that, if not properly maintained, the rotors presented the possibility of failing, thus creating a legal liability. However, M coupes produced for the Canadian market were equipped with the floating rotors. See similar questions...

Did you replace all of those little missing or broken plastic pieces inside and out? Do all systems work? Windows, locks, seats and sunroof all probably at least need lubrication. I take all of mine apart, clean and relube. See similar questions...

Every time pads and shoes are replaced, the drums and rotors should be resurfaced. Resurfacing not only provides a machined surface for your new brake pads or shoes, but also trues the rotor to the hub and the drum to the axle. This eliminates pedal pulsation and extends the life of your brakes. All 5 Winchester Auto Stores can turn your drums or rotors 7 days a week. See similar questions...

Car discs are totally different, you skim the surface to get rid of the hard skin that builds up & to make the disc flat again. Cast iron car discs are also very heavy which would add excessive weight to a motorcycle engine powered buggy. Making a disc out of steel means that the steel has that "Hot worked" scale on the surface. See similar questions...

No. Generally, you cannot use any larger diameter rotors, because from the factory the rotors come as big as they can be. See similar questions...

Another religious issue... In general: NO, unless your rotors are badly scored. If they are warped, replace (it's cheap and easy to do). Call places like APS & WolfSport. Note: If you take the rotors off yourself, turning them at a machine shop costs very little. See similar questions...

Due to the inbuilt safety cut out, the control unit must be calibrated before the helicopter will fly. To enable this, you must adhere to the following procedure: Move the left stick and trim on the transmitter to their lowest point (for mode 2 - right stick on mode 1). Once you have followed this procedure the LED on the control unit will flash red then green, then stay green. The helicopter is now ready to fly. See similar questions...

While we recommend connecting to the turn signal / brake lines for best performance, the unit operates still functions without them. The turn signal is used to tell if a change between lanes is intentional. If it is not connected, you have the option of suppressing all warnings when crossing a dashed line. It will still warn if you begin to cross a solid boundary. See similar questions...

Of course we do! Sturgis Wheel offers the 11.5” rotors in both the 920 stainless steel, both polished and glass bead finish, or 2 pieces with a billet center. They are available in all of our latest designs. The 2 piece are not “floating rotors”. They are for a show bike look, with a super shinny billet center. See similar questions...

Our 1 piece rotors are shipped with a glass bead finish. We do offer polished rotors at an additional charge. The 2 piece rotors have a highly polished billet center. See similar questions...

Clessie L. Cummins, founder of the Cummins Engine Company, drove across the United States to demonstrate the viability of diesel engines in 1931. While descending Cajon pass in California, the foundation brakes on his vehicle faded and he and the crew of his truck were nearly killed. Shortly after this experience Clessie first conceived the idea of using the engine to slow a vehicle going down hill. See similar questions...

Slotted rotors have slots on their surface. These slots provide additional surface area which help dissipate heat better and also clean the pads. The rotors can cast slotted or slotted after they were made. Cast slotted rotors tend to last longer and be more cracking and warping resistant. See similar questions...

If no excessive pulsation, lateral runout or surface scoring exists and physical dimensions of the rotor are within manufacturer's specs and you are using the same type and manufacturer of friction material- rotors machining is not necessary. See similar questions...

Exhaust brakes are widely used in the medium/heavy duty truck market, and Allison publishes guidelines for integrating exhaust brake controls with the TCM. This integration is necessary so that the transmission can alter its shift characteristics to maximize the exhaust brake's effectiveness and not adversely affect transmission operation when the exhaust brake is not in use. Allison Engineering has tested one manufacturer's aftermarket exhaust brake on a Duramax equipped pickup. See similar questions...

You can turn tooltips either on or off through the "My Profile" page under "My Menu." In the "Settings and Options" section, you will find a field named "Enable Tooltips". Turning this field to 'No' will disable tooltips where as turning it to 'Yes' will enable them. See similar questions...
