Hand­brake fail­ure

Car Mechanics (UK) - - Tales From The Workshop -

I am not a fan of elec­tric hand­brakes, not only be­cause I pre­fer to have a lever to grab and pull, but also be­cause they are more ex­pen­sive to fix when things go wrong.

This Re­nault Me­gane with an elec­tric hand­brake was a typ­i­cal ex­am­ple. The unit had failed not be­cause of a break­down of the elec­tric mo­tor or con­trol unit, but due to frayed and stick­ing ca­bles. Un­for­tu­nately, the ca­bles are not avail­able sep­a­rately – and to re­place the com­plete unit it’s £477.

The unit is not com­pli­cated to fit and sim­ply bolts un­der the ve­hi­cle. How­ever, it then needs to be ini­tialised us­ing a di­ag­nos­tic scan­ner. For­tu­nately, our scan­ner could carry out this op­er­a­tion, sav­ing a trip to a main dealer and the as­so­ci­ated costs.

An elec­tric mo­tor con­trolled by its own elec­tronic unit op­er­ates the hand­brake ca­bles.
