hi all,today I drove our HQ van and although it has a good pedal it doesn't have good brakes like the monaro,it really feels like it has grease on the brake pads and was worse when we put the trailer on it.I found a receipt for a recond brake booster in the van when I bought it and it has new rear wheel cylinders but still has bad brakes,doesn't seem to make any difference how hard you press the pedal.Any help or ideas would be appreciated thanks
