Q: How to replace the rear brake line on Cadillac CTS?
A: To change the rear brake hose open your vehicle and first remove its left front wheel assembly. Cleaning both brake hose and pipe components removes debris and foreign objects before capping the outlet with a rubber plug. Hook a flat tool under the brake hose retainer and remove it from the brake hose crossover pipe connection. Eject the brake hose from its frame placement and the caliper bolt from the brake caliper before taking the brake hose out of the vehicle. Strike the threaded brake hose end onto a towel to remove the gasket and discard the 2 stuck copper gaskets from the brake caliper or brake hose end. Insert a rubber plug into the brake caliper bolt hole of the brake caliper. Install new copper gaskets when joining the brake hose to caliper bolt socket. Connect the brake hose, new copper brake hose gaskets, and brake hose bolt together on the brake hose before installing the brake hose to caliper bolt on the brake caliper. Tighten the bolt to 50 n.m (37 lb ft) without twisting or kinking the brake hose. Fit the brake hose on the frame structure before placing the brake hose retainer on the brake hose and taking off the rubber cover from the crossover pipe end. Then insert and tighten the brake pipe fitting onto the brake hose to 18 n.m torque. To complete the process drain the brake fluid from the system then put back the rear wheel parts and lower the car.
Q: How to replace the rear brake line on Cadillac Escalade?
A: Begin brake hose replacement by lifting and propping up the vehicle followed by taking off its tire and wheel components. After clearing dirt from both brake parts put rubber caps on the exposed pipe end to prevent further brake contamination. To disconnect the brake hose safely twist the back up wrench into the brake pipe fitting while plugging or capping of the exposed end. Take off the brake hose retaining clip from its bracket and remove the brake hose through the bracket. Twist loose the brake hose to caliper bolt on the brake caliper and discard the 2 stuck copper brake hose gaskets. Install the brake hose bolt to the brake hose with 2 new gaskets and fit in the brake hose to caliper bolt with 2 new washers. Tighten the bolt to 40 n.m (30 lb ft) with proper brake hose alignment. Fasten the brake hose into its designated mounting bracket by placing the brake hose retaining clip over it. Secure the brake pipe fitting end with a wrench at the brake hose end. Keep the mounting bracket and brake pipe from bending as you connect the brake pipe end to the brake hose and tighten it to 25 n.m (18 lb ft). Seal and install the tire assembly back onto the vehicle and check if the brake hose has contact with suspension or tire parts. Correct problems before lowering the vehicle.
Q: How to Service and Repair Brake Lines Using the J 45405 Brake Line Flaring Kit on Cadillac XLR?
A: Use J 45405 Brake Pipe Flaring Kit along with protection methods from brake fluid irritants while using double-walled steel pipes to avoid brake system breakdown. Check the brake pipe location for replacement before freeing it from its retainers when needed. Choose a suitable location on the brake pipe that avoids bends and mounting points then measure the required section replacement length including 6.35 mm (0.250 in) for 4.76 mm (3/16 in) diameter pipe and 9.50 mm (0.374 in) for 6.35 mm (1/4 in) diameter pipe flare additions. Use the pipe cutter provided in J 45405 to cut your brake pipe square before you take out the sectioned pipe. Put on tube nuts of suitable size after removing nylon coating from the brake pipe end using provided J 45405 coating stripping tool and forming both inside and outside diameter with J 45405 deburring tool. Connect the tube nuts first before sterilizing the brake pipe and J 45405 from impurities. To flare the pipe you should loosen the screw and install both die halves. Push the prepared pipe end into the die cage while tightening the clamping screw and create the flare using the forming mandrel to check the diameter. The flare needs 6.74-7.10mm (0.265-0.279in) measurements for 4.76mm (3/16in) pipe or 8.57-9.27mm (0.344-0.358in) for 6.35mm (1/4in) pipe inputs. Use a brake pipe bending tool to shape the new part and connect it properly within its retainers. Afterward use the engine brake system to check for leaks caused by improper flaring.
