Getting ready to do my first Mini front brake job - 2005 27,000 miles -
Do I really need to do new Rotors also - per the dealer ??

Not a problem -I can do that - but are they really that 'soft' ??

Thanks

Hard to say without seeing your rotors, but I'd guess it would be ok to reuse the ones you have. Unless they are heavily grooved, cracked or warped.

Welcome to NAM.

 

Though there are quite a few opinions on this, a very good BMW tech friend of mine told me that the rotors are normally replaced after every 2nd or 3rd brake pad change--depending on how much wear is on them, but not every pad change. Based on the miles I've driven---65,000 miles on my first MINI and 84,000 miles on my current--it seems about right.

 

Just check to make sure that they are in spec (meaning they are well outside minimum thickness) and that there's no runout... You should be fine...

 

10-4 !

Like most things - " it all depends " !!!

 

What is the minimum thickness for the stock rotors?

Also, what is "runout" ? Thanks.

 

Runout is how much the rotor is out of round. Other times referred to as warped. An out of round rotor will cause pulsation in the brake pedal.
Minimum thickness should be stamped on the rotor.

 

it is stamped on the rotor you just need to find it

 

I see. Thanks. (More like "out of planar," right? )

 

I have seen OEM pads and rotors gone at 34K on a MINI driven very hard all the time. I have yet to see a set of OEM rotors last thru 2 sets of pads. At the most a set and half of pads. They come out of the box thin as paper and the OEM pads eat them up when driven hard.
If you want a pad rotor combo that will stop better, last longer and dust less send me a PM. If you are under the free pad/rotor plan at the dealer let them buy them, I won't give them a dime for OEM brake parts.

 

Thanks for all the info - since these are OEM , Im gonna replace rotors /pads -

I dont run hard much-unless I have to dust some 'euro-car' freak ( thats another thread) - but just looking for basic rotors/pads that will handle maybe 1/per year mountain trip( MOD ) - and last for at least 2 pad changes

Carquest rotors w/ 'blue' pads appeal based on other info -
Any obvious reasons not to go that way ??

PS - Shania loves COOPERs!!

 

Pads - 3.0mm

Front rotor - 20.4mm

Rear rotor - 8.4 mm

maximum disk run-out 0.05mm
