I broke one of my rear caliper bolts off tonight, and I want to take the hub off to extract the bolt a little easier, but I don't have the proper wrench for the big bolt on the bottom of the hub. The two other bolts are 17mm, but this one is quite a bit bigger...either 20 or 21mm. Can someone tell me what size it is, and where I should look for the proper wrench? Everywhere I've looked doesn't have anything between 19 and 22. Thanks.

Sears sell pretty much every size of wrench and socket up to like 3 inch.

Nobody knows what size that bolt is? I need to know soon. https://www.nopistons.com/forums/pub..._DIR#>/sad.png

i did that like a year ago.... i don't remember!

I'm going to drive the car into the Sears and I'll be all set. https://www.nopistons.com/forums/pub...#>/biggrin.png

wouldnt the manual say how big it is?

Can't you measure it?

i was gonna go look, but i just woke up and its already night time

yeah just measure it, i think it's around 21mm though.

Cut off the rotor like me https://www.nopistons.com/forums/pub...IR#>/wacko.png

I probably would have if I had air tools. The bolt in question is a 21mm. We couldn't get the axle nut off (bent a breaker bar and tire iron in the process) so we took the other end of the axle off and pulled it out a little so we could attempt to drill out the bolt. I drilled it and then broke the extractor off inside of it, so that whole idea was out the window. Long story short, I ended up taking the caliper apart and just replacing the pads that way...something that could have been done with the hub on the car.



Oh, and then my clutch went, so I still can't drive the car.

ouch!

buy measuring equipment when you goto sears
