    A4 B8 rear brake pads, how too?

    The rear pads need doing on my 58 plate A4 but the pesky electric handbrake is making it look nigh on impossible for a d.i.y,er .

    Can anyone recommend a link to a how too without using the plug in caliper re-set gizmo or am i going to have to stump up at a garage?

    There is a gunsons re set tool on e bay which might be worth a go?

    Look for someone near you with a VCDS. As far as I'm aware this is the only way of retracting the caliper to allow for a pad change unfortunately...

    You not considered buying vcds for both your cars, then its money gone towards a single tool to do many jobs

    You can do it without VCDS allthough its better if you have it.

    If your confident you can use use a 12v car battery to retract the pistons.


    The electromechanical parking brake is a 12-volt motor that engages and retracts the rear brakes.

    To retract the rear wheel parking brake, you will need access to a 12-volt battery and two jumper wires. One of the jumper wires should have an insulated clip on the end so you do not short-circuit the wires.
    When you are looking at the caliper you will see the brake line and electric wire/connector going to the rear caliper.
    Disconnect the electric connector from the caliper. Inside the connector on the caliper side you will see two medal pins sticking up. Connect the two jumper wires to the 12 volt battery.
    Take the negative wire jumper and connect it to one of the pins on the caliper. Then take the positive wire and touch the other pin without touching the other jumper wire and causing a short.
    If the caliper piston starts to push out, stop!, reverse the jumper wires. You should hear the parking brake retract and the piston not move.
    Continue until the caliper piston starts to spin, stop! Now push the caliper piston back in with a brake tool, c-clamp, etc. Replace pads as you would normally. After all the brakes have been replaced. Pump brake pedal until you have a firm pedal. Check the brake fluid. Then turn on and off the electromechanical parking brake a few times and you should be good to go. Very simple!

    Now that's what I'm talking about, there's always a way! Spare battery in the garage and plenty of wire about, pads ordered.....sorted.

    Some local jockey wanted to charge me £50 to connect the laptop to rewind the pistons and £47 to fit the pads?..no thanks.
