    Rotor thickness on RRC

    Hi All,

    What is the legal thickness for Disc Rotors on 1992 Range Rover classic before they need to be replaced.

    Looking around this forum DBA seem to be a good brand ... and whats everyone's opinion on discs being slotted only or both slotted and drilled.

    The Rangie just doesn't seem to pull up as quickly as I would like ..... looking at all avenues.

    If you just do slow work then I think plain. If you tow, are in the hills etc then slots. Not ever cross drilled due to cracking.

    Good high performance pads (not racing pads!) will make a big difference.

    One of the old Rangies from Davis Landys, with air suspension, just about put me through the windscreen the brakes were that good.
    Cheers

    Rotor thickness on RRC

    Hi All

    Finally have time to check rotors on Rangie

    Apologies for stupid questions up front ...

    I looking at link Justin did is it correct new discs difference between. New (24mm) and minimum before replacement is 22mm .... Is that sound right?.

    Is that thickness (22mm) same for solid rear disc??

    My rear right measures 12.5mm with Vernier calipers?

    I'm about to Jack up the LH Rear and check it

    No, the rears are solid and the dimensions are given above.
    It is difficult to measure them with Verniers due to the rim which sometimes builds up on the outside.
    try micrometer on the middle of the swept area.

    Regards Philip A
