Shimano 105 levers hard to press on the hoods?

I have just acquired a Boardman team carbon 2013 and noticed thats it takes a lot of effort to stop the bike when on the hoods.The leavers and brakes are 105's. It just takes a lot of force to stop and my hands just get tired so quick.I have average size hands. The pads look fine and are aligned properly and there very close almost touching the rims. There is no slack on the cables. The leavers don't actually move that much when you press them but still hard to stop. Theres no 'bite' i feel. I'm almost thinking the pivot point is in the wrong place on shimanos as i had no problem with Campags. If i'm low on the handlebars i can stop no problem but i spend 99% on the hoods. Any help would be great.
Wilier cento uno.

On the drops I have much more leverage so easy to stop. Not sure what a 'shim' is???
Maybe the pads are censored but they don't look too worn??
I think I may just have to take it to the local service shop and have it looked at. The bike is in new condition also.
Having no bite would automatically make me think there is something wrong with either the lever or the cables as especially with the front brake you should feel a definite bite even with the cheapest of brakes, and from the reviews the 105 brakeset is pretty good. (I used 2300 levers and unbranded callipers for 3 years and still the bite point is easy to feel)
If that is the case then I'd disconnect the brakes and give yourself some slack on the cables and see how free and smoothly the actual levers move, then you can start looking at poor cables, jammed calipers etc.
If you are just finding it hard to stop do you have any comparisons you can use against it- I assume you're not new to Road bikes!
On the hoods it can take a fair amount of force from the hands which will make them ache if you're not used to it, or on a long descent.
Otherwise my only suggestion would be to change your brake pads, but that won't improve your brake feel, only the stopping power which isn't very helpful without being able to modulate it!
It's when it makes contact with the rim. I used to use campaign veloce before and they where great. I've been off the road for about seven months so there may be some strength loss from my hands but these feel tough. I think the pads could possibly be the culprit.
Are these still in yours?

I have 105's on both my bikes, and like you spend the majority of time on the hoods. I find them very good stoppers.
For the price involved I would be tempted to fit new cable inners just in case they a catching somewhere internally. Other than that I would change the pads.
Maybe the cables are corroded or something ? It could be as something as easy as replacing the cable.
I had those same ones and I had the same issue, poor braking from the hoods, braking from the drops was ok. I would end up riding on the drops in urban areas just so I could pull the brakes enough. Tried brake blocks, changing the calipers etc and they helped slightly. Then I changed the STIs to Ultegra 6700 which have a different lever system and the braking from the hoods is now as good as from the drops.
I've just gone to Veloce which is miles better even with generic brakes and pads.

5700 needs the rubber shims to adjust reach, 5800 levers have an in-built adjustment screw instead, same as 6800.
When I had 6700 levers (same lever shape and pivot placement as 5700), I also found braking performance from the hoods to be poor. The newer 11spd. Shimano groupsets are much better in this department.
Try screwing in the barrel adjuster on the caliper a few turns, so that you have more lever travel before the pads hit the rim. This sometimes helps, as you can recruit more muscle power from your fingers when they are closer to a perpendicular angle to your palms.

I was wondering would adding high performance pads such as Swisstop make a difference? Herd so many good reviews about there stopping power?
Because I originally had 5700 and the braking from the hoods was indeed diabolical. Tried the usual things, new pads, even new calipers, no improvement. Eventually so frustrated with it I swapped the STI's for 6700 (which was expensive!) and the braking from the hoods was vastly improved.
I noticed it's harder to brake from the hoods with 105, but also I think the levers move less, so I'm guessing the cable pull ratio is different, but I don't think this is the sole reason, I think also when on the 105 hoods your fingers contact the lever much closer to the pivot point than on the sram levers, at least that's how it felt to me, which made it much more difficult to get any sort of strength into the lever
good news is I got used to it pretty quickly
5700 10 speed.
Do you think adding a shim would make a difference?
your hands will get used to it, when I first switched to 105 it almost felt like I couldn't stop at all from the hoods, but a month later and braking is fine
That is what I did for my son. Bought the shims but never got around to fitting them because he finds the above really sorted it out and he is now happy.
Thanks, Will try it.
Yeah, you may be right. I haven't been on the bike for over 6 months so i may just be a strength/staminer thing.
you can set the brake up so you are braking after very little lever movement (this tends to cause more forearm fatigue) or slacken the cable a little so the lever is closer to the handlebars before braking occurs (less stress on forearms/hands)
you can also set the pads up so they offer progressive rather than off/on braking by setting them at a slight angle (toe in)
This - I had my campag levers set up in a shop with so little initial travel, that braking from the hoods killed my hands. I added some play back in and it was back to normal.
Personally, I have the levers set so it's full on with the lever assembly about 5-10mm from touching the curve of the bars. That way, you hand is much further closed when you hit the resistance and squeezing is easier.
First fit shims in the levers to shorten the reach, second back the pads away from the rim a bit so your fist is half closed by the time the pressure comes on, lots more power from your fingers when their not fully extended, thirdly if you you still have the original hard shimano pads in bin them and get some decent pads like swistop salmons.
