We remove the elements of the brake mechanisms for replacement or repair

We discussed the replacement of the front brake pads in the article - Replacing the brake pads of the Renault Duster front wheels.

Replacing the front wheel brake hose

We replace the brake hose if it has mechanical defects - scuffs, cracks or breaks, as well as if brake fluid leaks through the hose.

After a run of more than 120 thousand km or 5 years of operation of the car (whichever comes first), it is advisable to carry out a forced replacement of the hoses of both front wheel brakes.

We carry out work on a flat area.

Remove the front wheel and securely fix the car on the stand.

Before unscrewing the brake pipe fitting from the upper hose end with a metal brush, clean the place of their connection from dirt and corrosion and apply an easily penetrating liquid like WD-40 to it.

If there are cracks, deep scratches, ripples, or other damage on the brake disc, it must be replaced.

The brake discs of the front wheels must be replaced in pairs, and the brake pads must also be replaced.

We install the car on a flat area or on a lift.

Remove the front wheel and fix the car on a stand.

Turn the steering wheel to the limit in the direction on which we dismantle the disk.

Remove the caliper from the brake disc and tie it with a wire or cord to the front suspension spring.

Before installing a new brake disc, we clean the mating surface of the hub from rust and dirt.

Install the disc in reverse order.

Tighten the screws for fastening the disc and the bolts for fastening the guide pads to the moments:

- screw for fastening the brake disc to the hub - 14 Nm;

- bolt for fastening the guide pad to the steering knuckle - 80 Nm.

Replacing the front wheel brake caliper

To complete the task, you will need tools: wrench 14, socket 18, large screwdriver
