Fit OEM bracket with no adjustment. Definitely stronger and smoother than the two piston original. Large fluid void in the caliper needs extra time and fluid to bleed but has top and bottom bleed options. I like the look of the new caliper through the wheel
Did a complete manual brake to power assisted disc brakes
Did a complete manual brake to power assisted disc brakes. Was very difficult finding the correct otems to fit a 1971 Duster but Chris and others were great to work with and we finally got everything correct. I appreciate their patience as we worked through rebuilding an old car. The entier team (tech and Chris) were great.
