Rubber bushes provide some vibration isolation. The Scenic unit has a single brake cable of approximately 1m which terminates in a triangular steel “shoe”which slides within a force divider assembly situated centrally on the rear axle. There are a pair of opposed Bouden cables from the force divider to the calliper assemblies.The unit itself is mounted behind the rear right hand wheel arch and within a plastic cage. This is often because repair attempts appear similar to a random selection of other faults We have found that Scenic Sometimes there are other codes as well as motor codes.

We will change both motor and relay in this case. If there is reference to a motor fault code, either existing or historic, we will treat it as a straightforward motor failure, If historic, we cannot be certain that the motor is the root cause because the relay is capable of causing the same fault as the motor, and both the motor and relay can become intermittent. We read the fault codes with our diagnostic machine. What Blue Chip Autotronics do to repair or refurbish these units Second hand units will often work, but for optimum performance on hill starts etc, they require re- programming in the same way as new replacements.

In the case of manual cars, it must “learn”information about the specific clutch pedal of that individual car.įor the second hand unit, you don’t know what it’s been through and may be only a short time away from failure. Other repairers have fitted second hand units from breakers.įor a new unit, you need to programme the replacement with, information about which engine and gearbox etc. When they go wrong, the received wisdom in the car repair industry has been that these units are irreparable and replacement with a new unit supplied by a Renault distributor is the only reliable long term solution. The cables also fail, as is discussed below. Apart from the relays, which are soldered into the PCBs, the PCBs themselves and the force sensors are very reliable and almost never fail except when there has been water damage. We suspect that the high current surges associated with motor failures over- stress the relay in particular, so we change it on a precautionary basis at the same time as the motor. The relay accounts for many failures and, in the case of the smaller later type, can often be seen to have a slight doming, or even a bubble of melted plastic on top indicating it is either at or near the end of its life. Another significant cause is the PCB mounted relay which changes the sense of the drive current for the motor, and hence its direction. The motors suffer from wear to the brushes Our experience is that complete motor failure can occur from 70,000 miles onwards and accounts for some 80% or so of failures we see.

This may require a lot of force to operate when needed due to failure locking the brake on, but can be reset undamaged for reuse. All electrical and electronic components except the force sensor and the motor itself are mounted on a single printed circuit board(PCB). There are three common PCB variants, and many variations in software What goes wrong? There is also an emergency release that releases a catch. What is inside the parking brake unit?Īll units contain the same powerful motor/gearbox combination. This drives a (turn- buckle and worm) gear arrangement to provide linear motion to operate two cables in all car models except the five- seater Scenic. All units have an emergency release cable entry gland on the opposite face. They are a sealed black plastic box of approximately 30cmx 15cm x 6cm with various mechanical cables and an electrical wire on one small end face. The box and it’s fittings inside Renault Scenic, Grand Scenic Laguna and Espace which controls and operates the automatic parking brake GeneralĪll the units described here are made by Küster for Renault and have a wide range of part numbers of the form 8200****** where the last six digits can be almost anything.
