This morning my Allante greeted me with a service brake switch message followed by Antil-Lock Brakes Disabled and Traction Control Disabled. I didn't have time to check it out but I did grab the manual and couldn't really find any info on the service brake switch error. I did find that it is the switch is used for the fluid level indicators. I am sure that the switch is the problem as I never got a low fluid message nor do I have a puddle of brake fluid under my car. My brakes were just checked about 3 months ago at the dealership and checked out fine.
so the question... what is involved with the brake switch?

Re: Service Brake Switch
I'm not that familiar with a 93, but on my 88 you ck the fluid level after depressurizing the ABS system. That will give you an accurate level in the master. Re ck the FSM regarding how to ck level. Could be as simple as topping off the master. The fluid drops as the pads wear, so brake inspections would only advise on percentage of pad remaining, not fluid level. I would also verify the float or switch in the master is not sunk, or sticking, giving a false indicator. Hope this helps.
