what I do, sometimes fustrating, is put a box end wrench on the nut. Just hope the wrench does not fall off. I do it very slow and carefully. Also use a motorized 3/8" drive wrench. The box end wrench will bind with something in the foot well box. I know this is kinda crude but I have done it manky times. I guess that I am lucky in this method.

I think folks may be getting confused between 'synthetic' and 'silicone' brake fluids, nothing wrong with synthetic and they are typically higher performing than non-synthetic, you however want to stay away from silicone (DoT 5), which is incompatible with earlier fluids and may older brake seals.

Cliff, Your helper under the dash holds the bolt (I think using 1/4 inch drive ratchet and extension and socket) while you turn the nut from outside. Doing it solo would be a damn hard job.

How do you stop top mounting bolt from spinning under dash? I can get a 13mm closed end wrench on the bottom mounting bolt under dash, cant access top bolt. Any tips appreciated! BTW-tough to find locally DOT 3 "Non synthetic" Brake fluid. Everything is synthetic. Had to order STP brand online! Thanks again!
