Brake caliper wear and tear?
 

Hey all! Hope everyone has a great Thanksgiving 2mrw!!! Well any who....

I was cleaning up the Z today and noticed these small cracks on the screws or lugs that are on all the calipers front and rear.

Should I be worried or is this just normal wear and tear?

It's just a rubber cap for the bleeder. Probably Cracking from heat cycles & the sun, not too much worry, but I would replace them.

As Felix 808 says, it's just a rubber cap. Only purpose is to keep dirt out of the bleeder valve. Not important to normal brake operation, but I'd replace them as allowing dirt into the system can cause big problems. Should be able to find replacements at any auto parts store - ask for "brake bleeder caps".

Edit: The problem with introducing dirt into the system only pops up when you bleed the brakes and your caps are not in that bad of shape. It's not like you need to run out today and get them. Just make sure the bleeder valve tip is clean (a few swipes with a small wire brush should remove any dust that may have crept past the cap) when you replace the caps.

Thank you guys for the quick replies! I will check that out this weekend! Happy Thanksgiving! Bless!
