The parking brake must hold the vehicle on a 25% slope when the lever is moved in the vehicle interior by 5-7 teeth (clicks) of the ratchet
To check the correct adjustment of the parking brake, find a flyover or loading ramp near the parking lot of your car with a height of H = 1.25 m with an entrance length of L = 5 m (Fig. 1).
This ratio corresponds to a slope of 25%.
In the absence of such a ramp for a simplified check of the parking brake, park the car on a flat area.
Place the shift lever in neutral, fully raise the parking brake lever.
Get out of the car and try to move it.
If you managed to do this, immediately adjust the parking brake actuator.
Adjusting the parking brake actuator
We adjust the parking brake drive after replacing the cables or the parking brake lever.
Hang out the rear wheels and securely fix the car on stands.
We remove the lining of the floor tunnel lining (article - Removing the lining of the floor tunnel of a Renault Duster car)
Having lifted the parking brake lever, we remove the cap of the lever lining that covers the adjusting nut of the parking brake drive (shown with the floor tunnel lining removed).
To adjust the position of the brake pads, press the brake pedal several times.
Hold it down and then repeatedly raise and lower the parking brake lever (when moving the lever, keep the parking brake off button on the lever pressed all the time so that the ratchet mechanism does not work).
At the same time, clicks will be heard in the brake mechanisms of the rear wheels from the operation of the mechanism for automatically adjusting the gaps between the pads and the brake drums.
If no clicks are heard when moving the parking brake lever, then increase the cable tension by tightening the nut on the threaded end of the front cable (see below).
Raise and lower the parking brake lever until the clicks in the brake mechanisms stop.
After that, we check the stroke of the lever, which should be 7-8 clicks of the teeth on the sector of the ratchet device of the lever.
If the number of clicks does not match, then turn the nut on the threaded end of the front cable by 10 with a wrench or a high head, increasing or decreasing its tension, adjust the stroke of the parking brake lever (for clarity, shown with the floor tunnel lining removed).
When the lever is fully lowered, the raised rear wheels should rotate freely, and when the lever is raised, they should be blocked.
A properly adjusted parking brake should hold the vehicle on grades up to and including 23%.
Replacing the parking brake cables
We replace the parking brake cables if they are broken or pulled out inside the shells, when the adjustment fails to keep the car stationary on a slope of up to 23% inclusive.
We carry out work on a viewing ditch or overpass.
We show the work of replacing the rear cable using the example of the left cable, we replace the right one in the same way.
We remove the lining of the floor tunnel (article - Removing the lining of the floor tunnel of a Renault Duster car).
To loosen the cable tension, raise the parking brake lever and with a 10 key, almost completely unscrew the drive adjusting nut on the threaded tip of the front cable.
Release the parking brake lever.
Remove the rear wheel brake pads (article - Replacement of brake pads for Renault Duster rear wheels).
Using pliers, we pull the front tip of the cable into the passenger compartment and, turning the equalizer, we remove the cable from the slot of the equalizer.
Squeezing with pliers, the petals of the latch of the rear tip of the cable sheath, we remove the tip from the hole in the shield of the brake mechanism and from the metal holder on the rear suspension arm.
Remove the cable from the two plastic holders on the fuel tank
Remove the cable from the plastic holder on the bottom of the body
In the car interior, with pliers, we squeeze the petals of the latch of the front tip of the cable sheath and push the tip out of the hole in the bottom.
This operation is not easy to perform, as you have to work in the cramped space of the bottom niche.
But given that we remove the cable for replacement, you can simply break the plastic retainer petals.
We bring the cable out of the hole in the bottom of the body
Also remove the right parking brake cable.
Install the rear parking brake cables in reverse order.
To replace the front parking brake cable, we remove the lining of the floor tunnel lining the tunnel floor of the car Renault Duster) and loosen the tension of the cables by unscrewing the adjusting nut of the drive on the threaded tip of the front cable.
Using a knife, carefully cut the carpeted floor behind the parking brake lever.
Disconnect the front ends of the rear cables from the equalizer.
Bending the cut parts of the carpet, with a 13 head, unscrew the two nuts securing the lever to the floor
Having lifted the parking brake lever, disconnect the wire block from the indicator switch and remove the lever.
Having removed the plug of the lever lining, with a 10 key, completely unscrew the adjusting nut on the threaded tip of the front cable.
Remove the front cable from the lever hole.
Having prying with a screwdriver, one by one remove the plastic clips of the front cable tip from the equalizer
And the end of the rear cables.
Remove the front cable from the equalizer.
Install the front parking brake cable in reverse order.
After replacing the cables or lever, we adjust the parking brake drive, as described at the beginning of the article.
