Shimano calipers mounting bolts too long and short for frame?

[Dirkitech]

Hello Hubland. I jumped in head first again and come across something new I don't understand.

I purchased a 10 speed ultegra groupset with direct mount rim brake calipers. In the photos below, the bolt and nut for the front brake is too short (the position of the photo is roughly the reach inside the fork mounting hole; the nut for the rear break seems too long and sticks out of the frame bracket (unless it is normal and should be like that).
Can I please get some advice on what to do to get the brakes mounted correctly?

Front:


Rear:

Stupid question, but are you sure you don't have the brakes back to front?

Long bolt goes in the fork, short bolt is the rear brake.

Technical correction - those are not direct mount brakes - those are good old SLRs.

 

The threaded portion of the brake is standard but the allen key nut on the back comes in different lengths to fit the frame & fork. A new brake set comes with a couple of options - your LBS should have hundreds lying around - take them a 6 pack of beer.

OP, I have a couple of different size nuts. Send me a PM and we can arrange for you to come to me in Rivonia with your bike and I will swap them out, free of charge.

Maybe make the same offer to Lance?

Open secret - we all do.

What he said.  Also chat with you LBS, they will have a bunch of different length allen key nuts, so you should be able to find suitable

the answer here is DISC BRAKES.

Unless you mean that I had the rear brake facing the sky last night  

The one caliper has a longer bolt to it so I assumed it must be the front one, otherwise I couldn't distinguish any differences.

Thank you for the correction- I just learnt something!

Fortunately unfortunately the frame doesn't have disc brake caliper mounts and the wheels are rim brake, but I know that was meant to be comic sans!

I went to see Loose cog today and he helped me with some different sized bolts for the brakes and some wisdom in setting them up correctly.

Thank you very much!
