how to: changing brake master cylinder

[snoopyloopy]

if you haven't guessed (in which case you haven't read my trollfest in the suspension forum), i changed my brake master cylinder. here's a little how-to from it in case anyone wants to duplicate my success (for once!).

yes, you will in fact need to open up your hood

and there's the target of our interests

remove the vacuum hose going to brake booster and the tree that holds it up and also the tree holding the cc cable (if your car has it) and vss cable

loosen (but don't remove yet) bmc from firewall (12 mm socket)

loosen brake lines (flare wrench = ++; it's a 10 mm)

now loosen it from the firewall the rest of the way and then loosen lines and remove quicker than possible

this comes in extremely handy right now. chances are you did indeed spill some fluid. spray spray spray. (but please don't try that if your engine is hot)

not NECESSARY, but will really make life easier later. bench bleed it. find some hose that fits (or maybe yours came with a bench bleed kit already and loop it like so)

clamp it down level
http://i5.photobucket.com/albums/y185/snoopyloopy/car/accord/P9270393.jpg

fill it with fluid and then give the piston a couple good pushes until you see most of the bubbles gone
http://i5.photobucket.com/albums/y185/snoopyloopy/car/accord/P9270394.jpg

then empty it or not. rush it into position

retighten the brake lines

now for the torque wrench
http://i5.photobucket.com/albums/y185/snoopyloopy/car/accord/P9270396.jpg

put on the firewall bolts and torque them down (132 in/lb = 11 ft/lb)

and that's it, you're done!

figured lol bleeding brakes ftl since no one ever helps me lol

^yeah i dont like it when no one helps either lol, i wonder if sticking a 1 way valve on the hose will let you do it by yourself. i use vice grips to undo the lines instead of a 10mm ring spanner, less chance of it slipping and ruining the nut thingy
