Replacing the brake elements of the rear wheels Renault Duster

We replace the elements of the brake mechanisms of the rear wheels in the event of faults or upon reaching the calendar service life.

We have examined the replacement of the shoes of the brake mechanisms of the rear wheels in the article – Replacement of the brake shoes of the rear wheels Renault Duster.

Removal and installation of the brake drum

We remove the brake drum for its replacement in the event of damage or wear of the working surface (maximum permissible internal diameter of the drum 229.5 mm), as well as for monitoring the condition of the brake mechanisms, replacing the brake shoes and the wheel cylinders.

Measurement of the internal diameter of the working surface of the brake drum

The removal of the drums of the 4x2 and 4x4 vehicles is described in the article – Replacement of the brake shoes of the rear wheels Renault Duster.

Replacement of the wheel cylinder of the brake mechanism of the rear wheel

We replace the wheel (working) cylinder of the brake mechanism of the rear wheel in the event of a decrease in the braking efficiency of the wheel due to jamming of the pistons in the cylinder or a leak of brake fluid through the sealing collars of the cylinder.

We carry out the work on a level surface.

We remove the rear wheel and securely fix the vehicle on a support.

We remove the drum of the brake mechanism and the brake shoes (article – Replacement of the brake shoes of the rear wheels Renault Duster).

Before unscrewing the union of the brake pipe from the opening of the cylinder, we clean their joint with a metal brush from dirt and corrosion and apply to it a penetrating liquid of the WD-40 type.

We remove the cap from the bleed union.

We install a new wheel cylinder in the reverse order.

After installing the brake drum, we bleed the hydraulic brake drive (article – Replacement and bleeding of the hydraulic drive of the brakes and clutch Renault Duster)

Replacement of the hose of the brake mechanism of the rear wheel

We replace the brake hose in the presence of mechanical defects on it — scuffs, cracks or ruptures, as well as in the event of detection of a leak of brake fluid through the hose.

After a mileage of over 120 thousand km or 5 years of operation of the vehicle (depending on which occurs first), it is desirable to carry out a forced replacement of the hoses of both brake mechanisms of the rear wheels.

We carry out the work on a ramp or an inspection pit.

Before unscrewing the unions of the brake pipes from the end pieces of the hose, we clean their joints with a metal brush from dirt and corrosion and apply to them a penetrating liquid of the WD-40 type.
