Need brake help!

[Gasket97]

While trying to bleed my brakes I snapped off the bleeder screw on the left rear wheel so I need to replace the wheel cylinder, is there any way to know what bore size the wheel cylinder is without removing the drum, it is a 1988 subaru gl with 3AT transmission and push button 4x4

The whell cylinder is about 10-12 dollars a piece.  Do not bother repairing it.

 

Good luck,

Sam

The bore size should be stamped on the wheel cylinder usually on the top of it. You will have to pull the drum and clean it up too see. Just a guess here but since your car is a 4wd wagon and auto (heaviest of the lineup) it would likely take the larger available size. I think thats 3/4.

I go through this drama every time I change a wheel cylinder. I always replace them in pairs. Plan on marinating them in PB and if possible have a good flare nut wrench, otherwise you will be making brake lines too.

3/4  is for the 4x4     5/8  is 2 wd

5/8 is more likely for the EA81 2wd hatch n coupe or something like that. Ive always replaced my EA81 cyls with 11/16 units which are probably the smaller ones for the 2wd ea82 cars.

Thank you guys, I'm not trying to fix it I'm going to replace it but I won't have the tool to remove the drum until I see my dad and I'm trying to get the part before if I can because there are two sizes available
