oystero · 10-12-2013, 08:28 PM

Thanks to Dave who started the Aus M3 thread (http://www.m3post.com/forums/showthread.php?t=886811). I thought i share another alternative BBK besides the other big players (Brem/AP/Stop).

Summary:
Front 381mm (15"), 6 Piston lightweight aluminium calipers
Rear 356mm (14"), 4 Piston lightweight aluminium calipers

Refer to http://www.harrop.com.au/brakedetail...=BK-ULTIMATEM3 for product details

Let the pictures do the talking

Was told standard bedding procedure (assuming you referring to initial break-in ?) => 7-10 runs of 30-100-30kmh

Bedding and bleeding are not the same...

Bleed using normal procedure (old fashion bleeding), no other special procedure.

Very good question!

Just had a look in the other thread looks like it's priced similarly to a Stoptech kit.

Will get you the answer tomorrow when I have the car up.

Hi Harold,

The bleeders on all calipers are in the inner half of the caliper and the holes in the outer half are machined there to carry out drilling of internal passages within the caliper which is why they are plugged up once manufacture is completed.

For this kit, the external crossover tube is machined internally within the caliper.

I will upload a photo tonight.

How do you get the all the air properly out of the outer half of the calipers?

What's your rear diffuser? Looks killer.

oystero · 10-21-2013, 04:27 AM

Photo did not come up clearly on the phone

the caliper bleed passages are all linked internally in the caliper and the inner bleed nipple is at the highest point

Guess to answer your question it will take "slightly" longer to bleed with 1 bleed nipple compared to 1 on each side like the brembos

Thx !! There is heaps of space on the 18" TE37

My guess is if the 18 can clear brembo or even stoptech*, you should be fine. Always good to check with them with the wheels you have in mind for clearance.
