The diagrams below show the basic differencesīetween the SB, the TSB and the TS2 type disc brake calipers. Flat steel cover replaced raised steel cap. Covered short guide pin & 2 piece housing. Raised steel cap with O Ring (long casting).ġ0mm Hex Sacrificial adjuster screw cap with domed rubber cover. Brake rotors are typically made out of cast iron. This, in turn, slows down the wheel and vehicle. The brake pad and caliper rub against the rotor and create the necessary friction to slow down the disc. Some differences found between Caliper types are as follows.Ĩmm Hex adjustment screw with flat plastic cover & exposed short guide pin, also 2 piece housing & raised bellow with hose clip (long casting).ġ0mm Hex Sacrificial adjuster screw cap with domed rubber cover. 2) Brake Rotor (Disc Brakes) Each wheel has a brake rotor which spins while the vehicle is moving. The principle for identifying all Knorr calipers is the same regardless of vehicle. Scania, SAF, Iveco, Hendrickson, Mercedes Benz, MAN & DAF. Knorr calipers are not only found on BPW trailer axles, they are used on many makes of vehicles ie. There have been changes to Knorr disc brake calipers over the years - some of the service kits are different between the different types.īPW classify the Knorr calipers fitted to their axle as Type A, Type B & Type C. Knorr classify the same calipers as SB, SN & SK types. “Right Hand Caliper” they are opposite to each other. “Left Hand Caliper” they are beside each other.Note position of adjuster & long casting. Generally you would view this caliper from the “Back View”, by doing this it is easier to identify the hand of the caliper, note position of long casting. If I.D tag is not locatable, then view caliper from the back in order to identify caliper hand. Cast numbers can help to Identify which caliper model / hand you have, these numbers will generally be in the same location.If the I.D tag is still intact you will find the “caliper model” and “part number” located here. We hope the photographs and information help you in assisting your customer to correctly identify what they need. We have included as much information as we currently have available, we will update our information as it becomes available. Meritor DX series are identified differently to Meritor Elsa series. The pistons in turn press the brake pads, which are friction material, against the brake rotors which rotate with the wheels. The way of identifying calipers is not the same for all brands ie. On BPW overslung suspension the righthand caliper is on the right side of the axle & the left hand caliper is used on the left side of the axle. On BPW underslung suspensions the righthand caliper is used on the left side of the axle & the left hand caliper is used on the right side of the axle. In all occasions it is important to identify the “hand” of the caliper, not the position. Not all calipers found at the LHF position are infact LH calipers, calipers can be used in opposite positions depending on suspension configuration. This information is a way of identifying different makes and types of Truck & Trailer calipers that we deal with on a regular basis.
