With today’s vehicle braking assemblies, it’s critical that all components are matched perfectly for the best possible braking performance. (Please note that the term ‘matched’ is relatively unknown by consumers, and is one you should become more familiar with.)
According to most new vehicle manufacturers, including Toyota, brake rotors must rotate with less than half the thickness of a human hair (.002″) of lateral runout, or “wobble”, in order for them to function safely and reduce any unwanted noise or vibrations. Brakes spinning with more than that tiny amount of lateral runout will make contact with brake pads, even when brakes are not applied. Soon, the continuous brake pad rubbing against the rotor will:
- Unevenly wear away at the brake rotor and brake pads and
- Create high heat from friction on brake rotors, causing the rotor to warp
Simply installing a new brake rotor or machining the rotor with a conventional bench brake lathe will not ensure a true ‘match’ between rotor and hub, and may result in brake pulsation within a few thousand miles.
So, what’s the best, most accurate method of doing a brake repair in Raleigh
Most car manufacturers today require dealers to use an “on the car lathe” when performing any brake repairs under warranty. Here at Creech Import Repair, we have the latest, top-of-the-line “Pro-cut” brake lathe. Some shops are charging extra to machine rotors on the car, but here at Creech we don’t. We just want to provide the best job possible at a reasonable price. We routinely repair brakes for Honda, Toyota, Lexus, Nissan, GM, Ford, Infiniti, Acura, Suzuki, Hyundai, and even Kia using the “Pro-cut” brake lathe whenever possible.
The following manufacturers require the use of an on the car brake lathe:
The following is a service bulletin posted by Honda:
“American Honda requires refinishing of the front brake discs with an on-car brake lathe that mounts to the steering knuckle. Use of an on-car, steering knuckle- mounted lathe is critical because it corrects runout of the hub and disc as an assembly. Experience has shown that very small amounts of runout, not felt as brake pulsation initially, will grow and become noticeable as the discs are subjected to heat and wear over time and mileage.”
