Craked Brembo Caliper

[Adz2332]

Hey all,

Pulled off my wheels to re-paint the brembos on my 33 GTR and the front driver has a a couple cracks in it.

Wasnt until i started spraying them red that i noticed the cracks. The black covered it up.

Has any one had this happen before?

Whats the chances of getting a single caliper?

Anyone know where to start looking?

Are any other models or different cars even that run the same brembos??

Is it just heat that causes it??

Thanks

ill try and get some up now. hard to see via pics...

[Adz2332]

heres the pics, cracks circled in yellow.

was hard to get them

not sure if they are as bad as im making them out?

[MrStabby]

Are you sure that's not just the paint? I'd be taking it back to bare metal for a proper look.

[GTRsean]

As above, looks like it has a fair few layers of paint on it. And usually it's the old paint that shows cracks like that.

The second pic is where the two halves of the caliper are joined together, not a crack

[Adz2332]

It's hard to see in the pics. In person it looks more then paint.

I'll sand it way back tomorrow n show pics

[GTSBoy]

Don't sand it. Wire wheel.

PROBLEM FOUND

Can anyone believe this??

Was filled with body filler!!??

WHY!?

[krzysztof]

wtf!

[GTSBoy]

That, children, is what happens when morons fit calipers that won't clear their wheels.

I would suggest that these would be pretty close to a throwaway now. Sadly.

Holy shit!!

You should probably keep the pistons etc in case you need to rebuild in future.

[Ronin 09]

not a good result.

i suggest that alarm bells should have been ringing when the bleed nipples, pistons and piston seals were all covered in that shit red paint.

bin.

Edit: did they come on the car or did you buy them. There's a fair amount of meat removed - i personally wouldn't be confident continuing to use these calipers.

[Adz2332]

Oh no they were black. I didn't notice until I started rubbing back. Again didn't take any notice. I sprayed it red and because of the colour saw the cracking lines. So rubbed it back to metal to find body filler. Got out the hammer and screw driver. Gave it a hit and out popped body filler.

Have since finished the other 3 and they are fine.

Very weird.

Now I have to find just one!

[Adz2332]

Came on the car mate

[Ronin 09]

yeah bummer - that's really weird that only one of the front pair is like this.

don't know how you'd go with getting a single; you might need to get a pair and keep the other one for parts if necessary.

plus if you are going to repaint then you don't need something that looks great - maybe you can save some coin there.

[Adz2332]

Yer true. It's weird it's just the one!

[Adz2332]

are 32, 33 and 34 front brembos different?

Do i have to get another 33 brembo?

[Miguelone]

32 and 33 are directly interchangeable part numbers, 34 numbers are different but probably just because they're gold.
