What size socket for the wheel cylinder nut???? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

Im working on the front brakes on my 1966 custom. What size socket do you need to take the wheel cylinder nut off??? 1 1/16 is too small and 1 1/8 is too big. 1 3/32 would be in between those two sizes but I have yet to find a source for a 1 3/32 socket. However, a 28mm fits nicely when tapped on with a hammer. But surley they did not use a metric size, or did they??? Can anyone shed some light on this situation?

what ever size gets the job done.......i recently replaced the two front wheel cylinders on my 66,and the new replacement wheel cylinders had diffrent size nuts then the ones i took off the truck, i dont remember what size's each one were but do remember the new ones were metric....yours may have been replaced in the past with metric ones, might all depend on where or who you get the new wheel cylinders from that they will be standard or metric.....as long as i can tighten or loosen them and they work and stop it doesnt bug me that they are metric....

Well....I agree, whatever size gets the job done. In this case it was the 28mm. However, when I bought my new wheel cylinder, it did not come with a new bolt. (I say bolt now because after removing the wheel cylinder "nut" I realized it is actually a bolt) I was just confused on why it would be metric?? It doesnt bother me, if it is metric. But, as you explained, someone could have changed it over the years. Have you ever seen an 1 3/32 socket or wrench? I found somewhere on the net that way back in the fortys and fiftys they actually made bolt heads, nuts and tools sized in 32nd increments. Just something I wondered about.

1 1/8 is what my 64 took to remove mine.

Also had to heat them up woth a torch to break them loose.

1 1/8 is what i also used on my 65 not 3 months ago. yours could just be corroded up from years and years of crud. I am pretty sure my truck was pulled out of a field and pieced back together with a lot of the original components like the wheel cylinders.
