Jason Girling uses seals that contain more natural rubber than domestic brake manufacturers. The Castrol brake fluid is kinder to the seals than other brands. If you change fluids from Castrol to something else, you can pretty much expect to have to rebuild master and slave cylinders and the calipers within a couple of years. This is not strictly a DeLorean issue. Lotuses have the same problems with brake fluids. I have noticed that GTLMA seems to have been withdrawn from the US market. There is a local Castrol dealer in Rochester who can't order GTLMA anymore. If you find some in a shop somewhere, buy all you can. If you don't want to, call me and I'll buy it...

I asked the guy at napa if he could order some for me so he looked and said that they don't have it listed. He then asked me why it has to be castrol dot 4 and not any other dot 4. I said good question and I'll find out. So why does it have to be Castrol? He said that the fluid is so regulated that there really can't be much difference between all of the brands. So what is so special about it? Thanks in advance....again.....................Jason #5903
