[giezy]

i am ready to do the hydo boost swap and just relized thet there is no port for my break pressure switch can i take the master apart and drill and tap it?

The master is used but works good and don,t whant to go buy a new one! it has the raised section where it should be. what does this switch control? cruise brake light?

any one?

i think it is for cruise pressure override incase the brake light switch fails also i think it will give you a brake warning light on the dash
