My brother-in-law just recently topped off his brake master cylinder with transmission fluid. Just like everything else the vehicle has been dumped off on me to fix. So my question is will transmission fluid damage the rubber seals in the brake system or can i just replace the fluid. Isuzu Rodeo
i would appreciate any info
