Page 5: Safety Instructions
Brakes contain numerous pinch points which can cause serious injury. Ensure all power sources are locked out prior to performing work. High Pressure Fluids: Kobelt lever brakes use high pressure hydraulics. Ensure all pressure is exhausted and the pressure source locked out prior to performing work. Hot Surfaces: Disc brakes are capable of making the surfaces of the brake disc dangerously hot when burnishing or during braking events. -
Page 6: Product Description
The diagram below shows a typical Kobelt caliper brake with all the major components identified. All of the Kobelt caliper brakes can be fitted with either air applied, hydraulic applied, spring applied with air released or spring applied with hydraulic released actuators depending on the required service. - Page 7 C and manufactured to required specifications. 2) Requires a minimum 4.34 in [110 mm] wide face Technical data and specifications are also available from our datasheet posted on www.kobelt.com the technical drawings in Appendix A.

International tolerance class. Allowable run out is proportional disc O.D. Parking brakes and emergency brakes with stopping times of 10 seconds or less are considered light duty. Ventilated discs are exempted from this requirement KOBELT MANUFACTURING CO. LTD MNL-5022-H.docx (rev A) - Page 10 The cooling air pumped through the disc must be exhausted away from the outer diameter of the disc to allow fresh, cool air to enter the inner vent opening of the disc.

All piping must be cleaned prior to connection to the actuators. Welded carbon steel piping must be pickled to remove the scale produced by welding. The connections to the brake actuators must be made by hoses of suitable rating to accommodate the movement of the brake levers. KOBELT MANUFACTURING CO. LTD MNL-5022-H.docx (rev A) - Page 12 The brake actuators are equipped with different sizes of pressure ports. Consult the technical drawing of the relevant model code for the specific port data. Tighten the port fitting to 15 ft- lbs [20 Nm]. Threads of stainless steel fittings must be lubricated before installing. KOBELT MANUFACTURING CO. LTD MNL-5022-H.docx (rev A)

The temperature of the disc surface must be monitored during the burnishing process and kept between 250 F (120 C) and 500 F (260 C). If the upper temperature is reached, pause the burnishing process until the disc is cooled to the lower limit. KOBELT MANUFACTURING CO. LTD MNL-5022-H.docx (rev A) -
Page 14: Torque Test
Before putting equipment into service, confirm that full rated braking torque has been achieved through load testing or a torque test against the drive motors. If full brake torque has not been achieved, continue burnishing. KOBELT MANUFACTURING CO. LTD MNL-5022-H.docx (rev A) -
Page 15: Operation
4.1.1 Pressure Supply Hydraulic versions of the Kobelt lever disc brakes require up to 1000 psi of pressure to operate. The pressure supply system must supply a hydraulic oil appropriate for the service conditions. Consult the table below for approved oils. -

The actuator seals should be inspected on a periodic basis. For air applied brakes apply air pressure to the actuators and listen for any hissing sound that would indicate a torn or ruptured diaphragm. KOBELT MANUFACTURING CO. LTD MNL-5022-H.docx (rev A) -
Page 18: Pin Wear
5.3 S ERVICE 5.3.1 Lubrication All Kobelt calipers, during assembly, are pre-greased on the shoe pin and saddle pin with a Lithium based NLGI 2 grease. These pins must be re-greased no less than once annually. 5.3.2 Stroke Adjustment Follow the procedure below to adjust the brake shoe running clearance back within specifications. -

4. Tighten screws ‘B’ When reinstalling the shoes and pivot blocks reinstall the shoe pin first to align the pivot blocks before tightening screws ‘C’. Tighten screws ‘C’ to 200 in-lbs [ 22.7 Nm]. KOBELT MANUFACTURING CO. LTD MNL-5022-H.docx (rev A) -
Page 20: Recommended Spares
ECOMMENDED PARES The spare parts kept on hand will depend on the severity of the service. As a minimum Kobelt recommends keeping the following parts for each brake in service: 1. One Lined set of brake shoes 2. One set of brake pads with rivets 3. -
Page 21: Warranty
If any part is found to be defective, Kobelt will replace said part FOB the Kobelt factory provided that any such defective part is returned by the Buyer with freight and applicable forwarding charges prepaid by the Buyer. -
