1 Check lining thickness (1) of brake pads IMPORTANT If necessary, use lamp (011) or mirror (012). If access is impeded by the mounted wheels, the measurement can be made on the inner brake pad.  
    For model 164, 166, 169, 172, 204, 207, 209, 212, 218, 230, 245, 251, model 216 (except 216.374/377/379), model 221 (except 221.074/077/174/177/179):  
    Measure thickness of brake pads. AP42.10-P-4253-01GZ
    SPECIAL TOOL Gauge adapter, for model 164, 166, 251 Figure
    SPECIAL TOOL Brake pad gage Fig 6
2 Remove stop plugs from check bores and check lining thickness (1) of brake shoes Vehicles with drum brakes.  
    IMPORTANT Use torch (011) if necessary.  
3 Install stop plugs for check bores Vehicles with drum brakes.  
4 Determine estimated remaining service distance of brake linings and agree on immediate or later replacement of brake pads/shoes with customer IMPORTANT If the check shows that the brake lining wear limit will be reached before the next service. AP42.10-P-4253-02A 
    IMPORTANT Expected remaining distance, take into account the driving style of the customer and conditions of use of the vehicle so that brake pads do not wear out before the next maintenance service
