I just had new brakes and etc day before yesterday. Then yesterday the digital instrument lights go off when I apply the brakes. They just start getting dim as the brake is applied. Then last night I noticed the dash light for the speedo and etc was out. When brakes not applied the digital lights work fine. Could this be just a fuse or something from the brake job? 93 STS Seville Northstar

Today I noticed that not only do the instrument panel digital lights go dim when applying the brakes, but the left front parking light will come on when applying the brakes (just the left one) If the headlights are on then the left parking light will go off when the brakes are applied and the left signal light does not work when the brakes are applied. Could this be a ground or a sensor wire that was not hooked up after working on the brakes????
