Metalnerd Rear Brake Tool is required for rear brake jobs on VWs and some Audis from 1989 through Mk7 that use a manual parking brake handle. These calipers need to have the piston rotated at a specific rate when being reset or else the parking brake mechanism will be destroyed. This tool turns the piston while forcing it back into the caliper.
Can also be used as a traditional wind-back tool for all normal style calipers as well.
All steel construction, zinc plated to resist rust. Converts for handy front brake resetting too. Includes a flat wrench, hex key and photos. BONUS - the wrench handle has a thin 15 mm spanner wrench for caliper guide pin removal.
