Hi Guys,
 
I have had a persistant squeak in the rear brakes so decided to pull off the wheels and work out why.
 
Turns out I have a heap of runout on the rotors.  About 2-3mm which is heaps.
 
I ended up using protex rotors instead of DBA/RDA so could this be an issue.
 
I have a set of RDA's rotors as well but they seem to have a smaller ID than the protex ones so I'd need to get my axles machined further to fit them.
 
Has anyone had the face of the axle machined as well to ensure the mating surface is flush?
 
Anyone have any ideas on what I can check?
 
Cheers

Does the who wheel wobble or just run out in the rotor?? Could be just a cheap disc...
If the whole wheel wobble I would look at your axle...

Didnt check the wheel. Good idea.

How do you check the axles?

Hi Matt
If the axle flange is even slightly too large the rotor hat will not sit flush against the axle flange.
You also need to make sure a small chamfer is machined on the outside edge of the axle flange (can be done with a file if need be) as there is a small radius on the inside of the rotor hat which may also prevent it seating correctly.
Hope this helps.
 
 

Hi Paul,
That would explain it.  I'll check it out tomorrow

Where have others bought a seal kit from? Prices?

Thanks, Shaun.

Got mine from Bursons.  About $30.00 per side from memory.  You can get them on eBay too.

Hi Paul,  
New member so I can't PM, but I'm after some of your r31 brackets?  
Can you please send me details, ect 
 
 
Cheers. 

You have PM

Fixed my issues.  I had a friend machine another 1.5mm off the axle flange and now it all runs true. 
 
Cheers
