ok i put some new rear shoes on my 94 civic dx 5 speed. but when i took them off the right side the bottom of the master cylinder fell off. so i figured there got air into it. but i had to buy a new master cylinder for that side anyway because i couldnt get the bleeder valve open. so i did that and bled that right side. still the petal went strait to the floor? ive tried as much as i can think of. could it be the brake booster? it would be odd tho because it worked fine before i put the shoes in. do i need to bleed all 4 because it got air into its whole system? like right rear, left rear, right front, left front? please helpppp

yea I would go and bleed the whole system.. getting air pockets out can be super difficult at times..even when u think they are all out they arent. Good luck.
