i'm trying to replace my master brake cylinder on my 94 civic. but i seem to cant get the master brake cylinder off the break booster.. so how the hell do i get it off?

 

Remove the mater cylinder's cap.
Disconnect the 2 brake lines.
Remove the 2 nut that is holding the master cylinder to the brake booster.

From here it should come out, it might be a little stuck so carefully prey it apart with a flat head screw driver. Give that a try and let us know how it goes. Good luck

There's a rubber dounut seal in the hole at the back of the master, sits in the hole, it sticks sometimes, like he said, pry the thing off carefully, , don't forget to remove the old rubber as the new master should have a new one, don't use em both. You should bench bleed the master first before installing it, plug both holes, fill it fith fluid, pump the plunger till it gets hard and you can't pump it any more, then install it with the plugs in it, carefully remove one plug at a time to connect the lines, keeping fluid in it at al times. Then bleed your brakes well. There is a screwed ajustment rod on the top of the brake pedel lever under the dash, you may nedd to ajust it a little if it's not an oem master, to get the pedal in the right place, don't overdo it.

 

well i can say after 3 hours and a big *** can of Pb blaster i got it off with a hammer and a screw driver.. thanks for all the help! now its 5 am time to put the new one on and bleed the breaks with one person... i have a feeling this is not going to work!!!

 

and i [freak]ing broke a screw of the break booster.. damn it.. is anyone from atlanta around here??
