The maximum allowable runout at the rotor friction surface is 0.002 inch (0.050 mm) as stated by most manufacturers. If runout exceeds specifications, the rotor must be turned or replaced. Typical maximum rotor thickness variation (parallelism) specifications are ______________. Most manufacturers do not provide a specification for hub runout. Brake Rotor Specs. Some vehicles are particularly sensitive to rotor runout, so much so that as little as 0.0015 inches of runout can produce noticeable pedal pulsations. a. Set the dial to zero and turn the rotor. Mark the high and low spots of the runout. (0.08 to 0.13 mm) 9) The chamfer on the inside edge of 1. P.R.N. This is the amount of hub runout. A runout of 0.0005 inch (0.00254 mm) at the bearing flange could result in a 0.001 inch (0.025 mm) runout at the rotor friction surface. Sleeves add to runout The maximum TIR must not exceed the following specifications. System for data collection and monitoring in an industrial environment are disclosed. If the rotor is within specifications, the rotor will spin true without wobbling outside of an imaginary plane drawn through the hub and parallel to it. This condition may be felt under light, medium or hard braking or any one of them. See Photo 2. 1 m (in the center of the running surface). When space is restricted, a dial test indicator can be used in place of the illustrated dial indicator. Technician A says that the rotor should be loosened, rotated 180, and retightened. "If i saw a old dude with what appeared to be a cat over his mouth driving faster than me I'd stop driving fast." This is the amount of hub runout. Location: Idaho. Study Resources. Brake rotor assembled lateral runout (LRO) exceeding the maximum allowable specification can cause thickness variation to develop in the brake rotor over time, usually between 4 800-11 300 km (3,000-7,000 mi). Most manufacturers do not provide a specification for hub runout. The maximum allowable runout at the rotor friction surface is 0.002 inch (0.050 mm) as stated by most manufacturers.

Check pads and especially the caliper pistons to see if they are clean and moving freely.Also check the brake pad retaining pin to make sure it is not corroded or notchy. If runout is 0.2 mm (0.008") the result is equivalent to loss of a 1/2 oz weight which is noticeable. Its not when the pulsation is felt that is important, its the fact that it is present at all. FWIW (maybe not much), I always lubricated the surfaces and guides/pins with a LITTLE Never-Seize prior to reassembly. GVWR: 5700 Lbs. If the bearing flange has a runout, that runout will be magnified at the rotor friction surface. The different specs are explained below. Total run out controls the entire surface simultaneously hence it controls cumulative variations in circularity, coaxiality, straightness, taper, angularity, and profile of a surface. Page 1 SERVICE MANUAL Challenger 550 & 750; Page 2 Foreword Brief introduction to the service and maintenance handbook for 550/750 Challenger UV This manual gives methods to check, maintain and repair the Cub Cadet 550 & 750 utility vehicles (UVs), and supplies some relevant techniques and performance data.
