How to replace the front brake line on Chevrolet Trailblazer?

The first step to replace front brake hose requires unbolting the retaining bolt attached to the frame. Protect the exposed brake pipe fitting ends by installing rubber caps or plugs to block out the loss of fluid and contamination. Start by removing the brake hose bolt installed on the brake caliper assembly then remove the brake hose from the vehicle. Throw away copper gaskets while you take away metal gaskets from the brake hose ends and brake caliper. Before mounting the brake caliper bolt a new copper gasket needs to be applied to the brake hose and bolt then tighten the assembly at 44 nm (33 ft. Lbs.). Screw the brake hose retaining bolt into the frame before tightening it to 20 nm (18 ft. Lbs.). Connect the brake pipe to its matching brake hose while tightening the fitting until it reaches 20 nm (18 ft. Lbs. Torque). The process consists of filling the brake master cylinder reservoir followed by bleeding the hydraulic brake system before completing front tire installation and motor vehicle descent.

How to Service and Repair Brake Lines Using the J 45405 Brake Pipe Flaring Kit on Chevrolet Trailblazer?

The J 45405 Brake Pipe Flaring Kit (J 45405) is required to service brake pipes while using double-walled steel brake pipe prevents brake system failure. Check the replacement area of the brake pipe then free it from any retainers when necessary. Decide on a proper section point for cut and avoid both bends and mounting positions by also measuring the replacement pipe length that includes flare dimensions at 6.35 mm (0.250 inch) for 4.76 mm (3/16 inch) diameter pipes and 9.50 mm (0.374 inch) for 6.35 mm (1/4 inch) diameter pipes. 6.35 mm (0.250 inch) flares are required for 4.76 mm (3/16 inch) diameter pipes while 9.50 mm (0.374 inch) flares are needed for 6.35 mm (1/4 inch) diameter pipes. Follow the J 45405 instructions to cut the brake pipe exactly with the provided pipe cutter. Use the coating stripping tool's proper blade to remove nylon coating from the flaring area but avoid damaging the metal. The de-burring tool from J 45405 should be used to chamfer both brake pipe outer and inner diameters before installing tube nuts. First clear both the J 45405 and brake pipe from all particle debris before opening the clamping screw to insert the appropriate die set into the die cage. Insert the prepared pipe for flaring into the tool and secure the clamping screw. Use the appropriate forming mandrel followed by operating the lever of the J 45405 device to form the tube flare before performing the process again with the finishing cone. Check the flare's dimensions and shape by unscrewing the die clamping screw then continues with the inspection. Flares measure 6.92 mm (0.272 inch) for pipes of 4.76 mm (3/16 inch) diameter while measuring 8.92 mm (0.351 inch) for pipes of 6.35 mm (1/4 inch) diameter. Proceed to shape a new pipe with a suitable brake pipe bending tool if required and install it with suitable unions while securing it to retainers before bleeding the hydraulic brakes and probing for leaks by starting the engine and test applying the brakes with assistance.

The Brake Line in Chevrolet Trailblazer car is used to carry brake fluid that is pumped from the master cylinder to the brake caliper pistons as a means of powering the hydraulic brake. This system makes it possible to stop or to slow down whenever use of the brake pedal is made. In Chevrolet Trailblazer car models of the past years, different types of Brake Line where used such as metal brake line and rubber brake line. Metal brake assisted by brake lines used to corrode especially in wet or winter situations and this causes the fluid to leak and hence reduced hydraulic pressure. On the other hand, rubber brake hoses may face mechanical damage or internal deterioration or improper fitting hence reducing its performance. For better performance, one may change to braided stainless steel Brake Line, this gives the driver better feel and sensitivity during track day among others.
