My first brake booster lasted for 275K miles and 25 years. 2 replacements have failed in the last 5K miles in 1 year. First replacement was new but of unknown origin. Second one came from England and billed as the best replacement. (While it lasted it seemed to work as well as the original). Any suggestions?

I had a TRW one put in as the master was leaking into it. Also did the D90 front caliper & rotor conversion. The brakes are really strong now!

Was this on a D1? I am looking on the TRW web site and there is nothing there for a D1 as far as a booster. I want this set up also - my brakes are not great...

I am in the process of making a hydraulic conversion. I have had the same experience... and even when they work... they are for sh!te. The conversion is using the hydraulic booster from the venerable 1999-2003 (and many more) Ford Powerstroke diesel pickup truck. I am not quite done with the conversion adapter (it's taking some time to craft it via Fusion 360, CNC and all that), once I am, I will report back to my prior thread on the topic.
