Hey guys
I just did a brake fluid change and was wondering... should you do this with the ignition on (to enable the brake booster - (just thinking, is the brake booster even enabled without the engine running? Haven't tried that one), or with the ignition off (assuming the engine doesn't have to run). I'd assume if anything, having the brake booster activated would only assist in reducing the effort to expell the fluid as opposed to expelling additional air from the system. Any thoughts?
