ACDelco Professional 18E1124 Rear Drum Brake Wheel Cylinder

10/10

wheel cylinders for 1957 chevrolet 210 perfect fit. installed and bleed lines DONE

Fit was perfect, great price and worked as designed.

the trick can be removal of previous unit . patience is the key to not cross thread , mounts as oem does.

It was very disappointing to replace all of the brake parts and this one cylinder leaked like crazy

Installed this cylinder quickly and easily! Exact replacement for the original. Great value.

Perfect Replacement for 63 Corvette

They're wheel cylinders..... Not too complicated. Not real pleased that AC Delco moved everything to China, just means I'll buy less of their products. One thing that irritated me to nearly the point of returning them, they're freaking METRIC bleeder screws..... You used to be able to do all of the work with a 3/8 wrench. 3/8 wrench for brake line, 3/8 wrench for bleeder screw, 3/8 for wheel cylinder bolts... Not anymore... Bleeder screw is 10mm. Every single nut/bolt on my 71 C10 is SAE, except the bleeder screws.... Most other Manf of classic car parts use SAE to stay uniform on things, all except AC Delco apparently. And before I hear that these fit other models, yes, they do, but nothing newer than say 1995-ish and just domestic vehicles that I'm aware of. And the mounting bolt holes are SAE.... So is the brake line port.
