Dat260 Posted August 1, 2004 Share Posted August 1, 2004 Hi Guys I'am in the process of upgrading to 300zx frt/bk brakes. I have the 81zx m/c for the swap (not installed) but I notice there a leak between the m/c and booster on my 260. Is it the booster thats needs to be changed and if it is can I put an 81zx booster for the upgrade? Regards, Ari Quote Link to comment Share on other sites More sharing options...
datsunlover Posted August 1, 2004 Share Posted August 1, 2004 I am wanting to do the same swap/upgrade this winter.. and I think the 'upgrade' is the actuall M/C, as it is a larger diameter cylinder.. so you'de have to swap it in place of your 260 M/C. But someone correct me if I'm wrong.. Quote Link to comment Share on other sites More sharing options...
Dat260 Posted August 2, 2004 Author Share Posted August 2, 2004 Thanks for the reply datsunlover. But I wanted to know if the leaking problem was due to a defective m/c or booster. Is there supposed to be a gasket of some sort between the m/c and booster? Regards, Ari Quote Link to comment Share on other sites More sharing options...
DaleMX Posted August 2, 2004 Share Posted August 2, 2004 If you have brake fluid at the junction of the M/C and the Booster then you have a bad M/C. That area should be dry. Maybe , just maybe a vacuum leak from the booster at the interface could cause the M/C to leak there, but I doubt it. Personally, I would check it anyway with the M/C pulled. Just dont pull on the shaft coming out of the booster or the reaction disk may drop off inside (hell to pay). Listen for vacuum leaks or spray brake cleaner into the front of the booster while the engine is running and listen for idle changes.
