    Long brake pedal on D4

    Hi All

    I'm new to Discovery, and wondering if it's normal for the Disco to have such long pedal travel before the brakes engage?

    I like a firm brake pedal, which is why driving my 16.5 HSE makes me nervous. Seems I need a lot of foot travel before the brakes begin to engage, then even more to get them to do anything meaningful. Vehicle has less than 3000 on the clock.

    Normal, or do I need to see the dealer?

    Long brake pedal on D4

    Doesn't sound normal but difficult to assess without actual values of travel distance. I find the brakes engage meaningfully as you'd expect and on average no different to other vehicles I've driven.

    One man's long pedal is another man's normal. Very hard to tell what you actually mean from that description but I've never noticed anything untoward and the brakes are brilliant.

    When I picked mine up from the dealer (MY13 D4 HSE) I did not notice any issue with the brakes after driving my old Pajero to the dealer as the trade.

    As previously said, contact the dealer. Brakes are too important to muck around with.

    Thanks for the feedback. I'll go see the dealer. I agree that what is "excessive" brake travel is subjective according to each user. As it is, pedal travel is around 100mm before it reaches full application. Pedal finishes about 30mm from floor. That's more movement than I'm used to in previous vehicles.

    Cheers all.

    That sounds very wrong to me. While they're no VW Golf (binary brakes), they're much better than that. Symptom you describe is akin to air in the system to me.

    Definitely sounds wrong to me. If anything my brakes are too responsive but more controlled, compared to other cars I've driven and have plenty of reserve without much travel.

    Feels wrong as well. Mid travel there's a whisper of brake, then they finally come on.

    Yes, pedal comes up if pumped.

    I'll get it to the dealer tomorrow. Hopefully no big deal to sort out, just a system bleed.
