sticky brake pedal on 2017 DS lux

Post by paulc » Wed Feb 15, 2017 5:49 pm

Hi Is anyone else having a problem with the brake pedal on their DS sport, if i press it lightly it overcomes some resistance and then acts like a normal pedal, this will happen if I haven't pressed the pedal for a while, if I press the pedal immediately after the first press it will not happen, I drive a few other vehicles but it does not happen on them, is this a common thing on the DS sport or is it just my vehicle?

That's something I've never heard of either on the forum or anywhere else.

It seems a visit the dealership may be necessary.

I think this happened to me after a long drive with no breaking. When I did brake it felt a little soft , but ok. The next brake seconds later was fine

Sticky brake pad? I have seen that on here before it was a stuck calliper pin

"When a braking pad sticks, it causes the brake fluid to boil. When the brake fluid boils, it expands and causes the hard brake pedal that one feels."

Do your brake pads look evenly worn on each side of the car?

Hi, this will do it if it stands in the garage and I Go to start it, this will happen when I push the pedal lightly and then leave it for a while it will do it again so the vehicle does not even have to move regards Paul

Ah ok I thought it was whilst driving, I'd guess it's servo assisted and perhaps loosing pressure ?

Edit losing pressure whilst parked

Hi, This is an update on the post a while ago, It has been in the garage for a total of 24 days and the final conclusion is from Land Rover Technical:-Having carried out further investigation with our Technical team here at Jaguar Land Rover, I would like to provide you with some information in regarding the functionality of the brake pedal; within the brake pedal application there are two elements which can affect the feel of the pedal. One being the initial pedal travel force and the other, middle position pedal travel force. Harder applications of the brake pedal increases the force, which is controlled by the brake booster and is preset by the factory. So the pedal itself is not sticking, it is the feel of the pedal through these stages that you are feeling. As such, your vehicle is performing to design intent.
I have driven a further 4 Discovery sports and 3 of them done it so Land Rover have deemed it as design intent, very poor considering the price of the vehicle and I have never driven a vehicle with this issue before.

I can't say I experience this on my car or on the loaner I had last year. Brake systems are setup with a higher initial force to overcome the latent friction of components and resistance in the rubber seals (called "jump-in"). This varies from manufacturer to manufacturer as it's part of their driving characteristics. My wifes Golf has a quite aggressive jump in (I think - I touch the brakes and hit the windscreen!) whereas the DS has a 'deader' pedal.

Maybe you've a sensitive foot and are detecting the 'jump-in' phase of the brake pedal, but in itself nothing to worry about.
