How to use
To replace a hydraulic hose bolt, first remove the wheel and clean the caliper area. Depressurize the hydraulic system following the brake manufacturer's service instructions. Unscrew and remove the existing bolt, inspect the hose olive and insert, and replace any damaged sealing components as required. Install the Clarks replacement bolt by threading it into the caliper or adapter until hand-tight, then torque to the brake manufacturer's recommended specification. After installation, bleed the brake system if needed and check for leaks and correct brake function before riding.
Usage recommendations
Use these bolts with compatible Hayes HFX and Magura Marta SL/Clara/Julia systems only. Always follow the brake manufacturer's service manual for torque values and bleeding procedures. Replace sealing olives or inserts when worn to ensure a leak-free connection and verify hydraulic integrity after each service.
