the 1inch difference doesnt realy show on this picture, but the stopping power was great with larger discs, locked up the frontwheels doing 120km/h/75mph with 225/45r17 wheels…
1. Remove everything, hubs/disc, caliper and brakeshield.
2. change brakeshield
3. switch the discs from the hub
4. get hub+disc back on
5. caliper in place
6. brakepads and bleed (the brakepads from w123 brakes fit the new calipers)
Nice pic and post. do you happen to know actual diameter of w123 and w126 ? 300mm ? and caliper piston size etc ?
