Lately I've been using my wifes bike every day to haul kids - as always I am shocked by how nice such a cheap groupset works - with one exception: the brakes are really awful. Especially from the hoods, there is little bite or feedback. I really have to work my hands to stop. Bike is not far from new, there is no cable drag etc.
This impression is not too different from the two 105 bikes I rented in the past few years, amazing drivetrain but afwul brakes compared to my Campy main bike. I also tried an Ultegra (just in a parking lot) which finally felt good with fast positive bite.

So I am wondering if it might be a good idea to upgrade the calipers. Do the levers match in cable pull? Or maybe just find some different pads from stock. Maybe something softer with better bite, I don't care about wear. Problem is it doesn't have removable pads...

Thanks

Usually new cables/outers and fitting some decent shoes/pads and giving the whole thing a clean and lube makes a massive difference.
Unless the main pivots have begun to corrode, then it's time to replace.

Make sure the ends of the cable housing are cut correctly, square.
Try compressionless housing.

Clean the rims and pads. Maybe oil or other contamination on thr rims/pads.

TRP Compressionless cables and Koolstop Salmon pads would make a huge difference.

Campagnolo CA500 Brake Pads Utter game changer. Condor have them and they fit Shimano carriers. I've done all the others.

I just remebered I had a pair of Record brakes for spares/backup. The caliper arms seemed to be same thickness, with a similar hole, so gave them a try. The fat alu nut didn't go in, but just barely - so 10 seconds with the dremel and all fine. The difference in feel with the Campy rubber is really big, the original pads were like wood in comparison. Not sure what is the Shimano reasoning - save a few cents on rubber or make more of a difference towards the more expensive groupsets. Other than this (and the weight) quite an amazing groupset for the money.
