Bleeding when pushing the front brake's pistons

If this is your first time doing brakes, I'd strongly suggest having a EXPERIENCED friend; who knows what they're doing help you out for your first time. Brakes are a pretty important component of your car and needs to function properly!!! If you don't have a friend like that, take the car to a professional. You don't know, what your don't know!
NO you DO NOT crack the bleed valve on your calibers! That's a surefire way of getting air into your braking system. There shouldn't be any junk behind your caliber piston, if you properly maintain your braking system. Brake systems flush-out every 3-5 years; Toyota doesn't recommend it but other OEM's like VW & Honda do.

I can watch plenty of videos on how to defuse a bomb; but that doesn't mean I would want to - the stakes are too high.....

Just my 2-cents.......

 

I disagree... Brake systems are very simple and straight forward and the fear related to maintaining them causes so called "Professionals" to charge hundreds of dollars for something that's a super easy 20 min job once you've done it enough times. It's not much different then changing batteries in an expensive machine. And changing brake pads most often doesn't require new rotors or bleeding the lines... Of course if you want to tru$t the expert$ about $afety...
