914World.com _ 914World Garage _ Caliper Rebuilds

Posted by: jim_hoyland Aug 8 2022, 09:19 PM

Two questions;
1. After watching the PMB rear caliper rebuild, I’m curious what’s involved in the front rebuild

2. Do the front 914 and front 911M calipers use the same rebuild parts ?

PMB has you covered on how-to for rebuilding the fronts too: https://www.pmbperformance.com/brakehowto.html

Fronts are very easy compared to the rears. Not sure if the parts for 914 and 911M are the same, but PMB has rebuild kits.

911 and 914/6 have a larger piston than the 914/4 none of the parts are the same.

Lastly: are the 911M rear calipers different compared to 911M front calipers
If Yes, what physical characteristics tell which is which ?

48mm 911 & 914/6 front
42mm 914 front
38mm 911 & 914/6 rear
