So i had replaced most of my front suspension myself - discs, calipers, pads, controls arms, and struts and one day i started to hear a noise coming from the front left tire.

Didnt quite trust it so i checked it out and i could pretty easily tell the brake dust cover was touching the disc and that was causing the noise and some resistance and tried to bend it away. It was a bit loose so i checked the inside and saw one of the two caliper base bolts wasnt there...

So i need to know the size/specs so i quickly get a new one. I figured the bolt missing allowed the dust plate to come lose and rub against the disc. I put all bolts in with an impact wrench and double checked everything, along with a trusted mechanics approval. And its about 20 minutes away from me so i cant really just go look at it.

 

Anyone?

 

So you are saying, that bolt was put in properly then checked by a mechanic and it still came out?

Take one of the other ones out and take it where ever and have it matched. They are all the same.

 

Well.. i dont think the mechanic went and torqued each bolt but he pretty much approved of everything (which i guess doesnt mean much). Anyway im going to a dealer tomorrow, hopefully they'll have it.

 

Did you ever find a resolution on this size? I have the same problem and have not been able to track down a replacement caliper bolt..

 

bolt sizes are specified in ASA...

 

Thank you for taking the time to reply back and answer my question! I hate to be overly ignorant, but I don't know what the ASA is?
