i was wondering if you could help me with the measurements of my bolt, the top bolt on my caliper is a regular bolt that can be removed with a 13mm socket but the bottom bolt for both driver and passenger (front) has a bolt with a hex shape indention and im trying to figure out whats the measurement of the hex indention so that i can get the part

 

Are you talking about your brake caliper? Pics would go a long way here, when you say 'hex indention' do you mean a socket cap bolt that you'd remove with an allen key?

 

yes one of the brake caliper bolts looks as if you need a hex key to remove it

 

or allen key whichever it called

 

Go to Harbor Freight and purchase a complete set

Telcoman

 

Are you on OE Brembos? If so, the entire caliper is powder coated after assembly, meaning no standard allen key will fit that socket head cap without stripping the coating off the socket cap section of the bolt (or stripping the bolt itself, or stripping your harbor freight chinesium alloy allen key).

Also, if it's OE Brembos you're talking about, I'd reconsider cracking those blocks open, or you may find yourself looking for a new internal crossover fluid seal that does not exist as a standalone replacement part. You can pretty easily find small Ø high temp o-rings, but... well it's your call if you want to risk it!
