crap news mate,
my front wheels locked up a while ago, i thought it was the brakes, got a piston repair kit,thinking it was the pistons, spent ages and ages changing them and refurbing the callipers, put them on, drove 10 ft out of my garage all happy thinking it was sorted, and the front wheels locked up again, turned out to be the diff fooked in the gearbox, i was gutted, i feel for you,
