Good morning folks -
Before I change out the master cylinder, i wanted to run this by everyone else and see if i'm missing something -
in my 5 speed D1 - Under any normal driving condition - brakes are fine (as fine as a Disco can get at least). but any time i am in a lower gear at higher RPM's for an extended period of time (i.e. going up steep hills on mountain roads/trails) the brakes go to the floor initially. they are quickly pumped up (one pump), but nonetheless, not good. i've never had to make any vacuum system repairs so i'm not too familiar with that. i feel like the high rpm's are related, as that is the only other common denominator. any thoughts?
