I got 2006 matrix awd. I removed brake drum and accidentally applied on brake pedal. Now drum doesn't fit back on. Also noticed wheel cylinder is leaking fluid a little. Please help, I had the same problem few days ago and mechanic but the drum back on but now I need to do it myself. I do turn the self adjustor or whatever it is but it doesn't work. Q side( where cylinder is leaking) its too far to fit inside drum
When that happens the wheel cylinder typically 'pops' (seals pop out), causing a leak. It would be best to install a new wheel cylinder.
So wheel cylinder is the reason why it doesn't fit back on? It feels like the side where I discovered leaking, that shoe is stuck and doesn't adjust or move at all
If the shoes were still installed when you did this they would have been pushed out as far as they could go. You would need to push the wheel cylinder cups back in, but as I said at this point you really should install a new cylinder.
Loosen the brake bleeder screw and press the brake shoes together. Then tighten the brake bleeder screw
Chuck has the proper fix. You have blown the seals out of the slave (wheel) cylinder and it needs to be replaced with a new one. Just pushing it back together is an invitation to a future wheel cylinder leak.
Wheel cylinder was ruined and was stuck on that side where drum didn't fit
Fix: remove old cylinder (spottys video) , make shoes go as far away from each other as possible( used adjustor), put new one on and bleed the brake line.
