Re: messed up on a ford explorer brake job
You should be okay. I've been doing brakes for better than ten years now on a regular, professional basis. I've never had a problem with ruining a master cylinder. I rarely open the bleeder screw when I compress the pistons even though I know there is a possibility of that happening. It hasn't happened so I've sort of passed it off as an old wives tale. I do however remove some fluid from the M/C reservoir before doing a brake job, just because I know for a fact I don't feel like washing off the firewall when I'm done. Brake fluid=bad for paint.
