Every six months approximately, lift the car and safely support it on jackstands to inspect the flexible hoses which connect the steel brake lines to the front and rear brake units as these hoses are quite essential and rather susceptible to cracks, abrasion, leaks, blisters or bulges and any of these should call for replacement of the affected hose with a new one; it will be advisable to use a light and a mirror while inspecting areas that can hardly To replace the front brake hose to start off, undo the brake line from the hose fitting using a back-up wrench and then remove the 'U' clip from the female end at the bracket and also removing the hose from the bracket. At the caliper end remove the bolt securing the fitting block, after that the hose and copper washers. On fitting a new hose, always fit new copper washers and before tightening bolt apply clean brake fluid to the threads of the bolt and ensure that the fitting flange goes under the caliper locating ledge before connecting the hose. Make sure the hose does not twist and put the female fitting inside the hose bracket and fasten it with a clip; next tighten the brake line to the female hose fitting with back-up wrench. After the installation, check to be sure that the hose is not kinked and does not come into contact with its suspension part by sharply turning the wheels to the left and to the right. For the rear brake hose, first way it with back-up wrench at both ends, then remove the U-clip, unbolt the hose retaining clip and put the female ends into the frame bracket without twisting. Screw the female end with the help of the U-clip and then fit the steel line fittings such that tightens the frame bracket. Refill master cylinder reservoir and carryout bleed procedure. When removing metal brake line, it is advised to replace it with the similar type, not to use copper or other type of tubing, there are prefabricated brake line available in auto part stores. If prefabricated lines are not available get recommended steel tubing and fittings, then you measure the old brake line and cut that of the new tubing flare the ends then fit the fittings. If necessary to put it through the desired shape, use the tube bender frequently to support the place where the line contacts the brackets with a safety clearance from other moving or hot parts. These steps are performing after installation, checking the fluid level of the master circuit, putting the fluid if available, bleaching the system and testing the brakes before operating it on the traffic.
