Failed NCT on brake imbalance

    Hey guys,

    Looking for some help, my car failed the NCT because of rear brake imbalance.
    The results were: 0.410kN (nearside) and 0.830kN (offside).
    The parking brake was 0.350kN (nearside) and 1.280kN (offside).
    The car is a 2001 suzuki swift.

    Looking for advice on the following

    - If I change the brakes will this fix it and is there a way to check if they are balanced without going to a garage

    - The rear brakes are drum brakes. So do I just have to replace the shoes or the drum as well?

    - If I do change the brakes would it be cheaper to go to a garage to check if they're balanced or just get retested at the NCT centre if it cant be done at home?

    Thanks in advance.

    When you remove the drums you need to check the wheel cylinders - they could be seized or beginning to leak.
    Any sign of leaking or sticking means that both should be replaced.
    I usually replace the wheel cylinders anyway when replacing the shoes because if a leak develops later you will have to change the shoes again plus the cylinders.
    As regards testing I would bring it for a retest when the work is done - and give the new shoes a few days to 'bed in'

    Ok I'll replace the shoes and cylinders so. Thanks for the advice.
