How to replace the front brake line on Cadillac CTS?

Raise and support your vehicle before taking off the wheel and tire to replace the front brake hose. Remove all dirt and foreign matter from brake pipe and hose fittings before putting a rubber plug or cap on the open pipe end to shield brake fluid loss. Fit a rubber cap over the brake pipe fitting to seal its opening while you remove it from the brake hose. Move the retaining clip onto the brake hose open end before removing the brake hose retainer using a flat-bladed tool. Take off both the brake hose from its bracket and the brake hose to caliper bolt from the brake caliper to access the brake hose. By tapping the threaded brake hose end onto a towel you will disgorge its gasket and eliminate the copper brake hose gaskets sticking to the brake caliper or brake hose end. Insert a rubber plug into the caliper bolt opening of the brake caliper. Insert the brake hose into position on the caliper bolt hole and connect new brake gaskets and the brake hose bolt. Insert the brake hose on its bolt into the brake caliper and fasten it by hand until reaching 40 n.m (30 lb ft) torque. Insert the brake hose through the brake hose bracket and keep its tapered end towards the pipe before installing the brake hose retainer. Twist off the rubber cap on the brake pipe end to install the brake pipe fitting to the hose but tighten only to 15 n.m (11 lb ft). Last, drain the brake fluid from the system after installation then place the tire wheel combination before lowering the vehicle.

How to Service and Repair Brake Lines Using the J 45405 Brake Line Flaring Kit on Cadillac CTS?

Service and repair of brake pipes requires the J 45405 Brake Pipe Flaring Kit (J 45405) while using only double-walled steel brake pipe to stop brake system failure. The first step entails checking the brake pipe area for replacement then removing it from retainers if necessary. Select a proper section point on the brake pipe which should be away from bends or mounting points and measure the replacement length using the required distance for flares between The required flare length is 6.35 mm (0.250 inch) for 4.76 mm (3/16 inch) diameter pipe while 9.50 mm (0.374 inch) is needed for 6.35 mm (1/4 inch) diameter pipe. 6.35 mm (0.250 inch) for 4.76 mm (3/16 inch) diameter pipe and 9.50 mm (0.374 inch) for 6.35 mm (1/4 inch) diameter pipe. Use the supplied J 45405 (J 45405) pipe cutter to make a square cut across the brake pipe. The appropriate blade from the J 45405 coating stripping tool must remove the nylon coating from the end of the pipe which will be flared without damaging the metal underneath. You need to use the provided de-burring tool in J 45405 to carefully chamfer both inside and outside pipe diameters. Begin by attaching tube nuts to the brake pipe followed by pipe and J 45405 cleaning from contaminants and proper die set selection for installation into the die cage. Place the ready pipe end into the die assembly before operating the J 45405 lever to create the flare followed by finishing the process with the second cone. Check that the flare matches the correct dimensions in terms of size and form. The required diameter is 6.92 mm (0.272 inch) for 4.76mm (3/16 inch) pipes while 8.92mm (0.351 inch) is required for 6.35mm (1/4 inch) pipes. Install the pipe with proper unions after you shape it with an appropriate brake pipe bending tool while keeping a 19 mm (3/4 inch) gap between components in motion. Finish the procedure by bolting the brake pipe back into its retainers followed by hydraulic brake bleeding and inspection under braking conditions.

The Cadillac CTS Brake Line is highly involved in supplying brake fluid from the master cylinder to the brake caliper pistons so that the hydraulic braking system may run smoothly. Metal brake lines are also vulnerable to both corrosion and impact and the end result of both is the creation of leaks in the fluid as well as the hydraulic pressure. Another component that can get physical and internal damage is the brake hose which in turn will impact the performance of the brakes. Should replacement be required then preformed brake line kits and corrosion protected stainless steel brake hoses can therefore be used for fitting. Replacing it with the braided stainless steel hoses will yield a better feel on the pedals especially in performance driving situations.
