a) looks to be the same as used on other GM cars as well (was an option on our '90 Bonneville).<P>B) Just pump the brake 25 times with the key off (better after sitting overnight). Believe a T-50 torx fits the top and it just spins off/new spins on like an oil filter.<P>There is a "thingie" that extends and inch or so up into the accumulator housing so you need to be careful when lifting off the accumulator.<P>Remember, KEY MUST BE OFF before pumping to relieve pressure. Good idea to wrap a paper towel around base in case all pressure not gone. Also when pressure is relieved, is a good time to check the brake fluid level in resovoir. May look low at other times but is not.<P>Master cyl. did move quite a bit when I changed mine - what do you hold on to ? <P>Note: seal is by o-ring, no need to play godzilla when tightening. About like a spark plug felt right.
