That rod (bolt) thru the middle that holds ur brake together gets too tight. You can disassemble and clean it or just loosen the nut on the front and watch em snap back to open position

SOURCE: Hi Everyone! I have a Shimano
If you are going to use the front triple crankset, then you need to use the 6603 components. These are for Triple set-ups.
If you intend to keep your bike a triple, then everything in the drivetrain must be the triple designation, hence the XX03.
If you want to change the crankset to a compact, then you can use the 6600 (double) equipment, but you will need to change the left (front shifter) to a double as well. The compact crankset, will give you virtually the same range as the triple and be much lighter and shift better.
The cassette: You can use any 10 spd cassette from Shimano or SRAM as long as the rear cog is no larger than 27. if you want to use a larger cog like a 28, then you will have to use the 6700 group, assuming yoiu want to stay with shimano ultegra.
Final Note: Since you are chainging everything, you may want to consider the SRAM Apex group, this gives you more gear ratio than the Ultegra, is slightly less expensive and around the same weight. Great alternative to Triple bikes.
Parts you will need to convert:
Front Derailleur (if changing to compact double or Apex)
Shifter set (if Apex)
Crankset (if Apex or compact shimano)
Bottom Bracket (if Apex)
The biggest thing is that Shifters and rear derailleur must be from the same company (shimano, SRAM, etc.) after that just make sure that yoiu use 10spd with 10spd, 9 with 9, and so on. Everything else can mix and match.

Testimonial: "Thanks v much......ok so will use my 6603 levers, 5603 Hollowtech triple chainset, then 6700 derailleurs (front and back) and 6700 cassette!!!!! "
It is apparently critical for the success of the pairing operation that initial power-up of the component to be paired be done cleanly, with little or no contact bounce when the battery is inserted. Since this is done with low power high frequency radio signals, interference and reflections can be an issue. If you have extraneous gear such as metal water bottle brackets mounted near the system controller / battery pack, remove it for this operation. Do not let anyone play with R/C toys within 30 feet while you are doing the pairing, and turn off Bluetooth devices to be really sure.
The graphics shown in the SC-7900 supplemental manual imply that the right and left shift levers are separate devices, but they are powered from the same battery and connected to the system at a single point. While Shimano's online documentation on this is rather sparse, the Di2 7900 system description says the system logic and communication circuits are inside the front derailleur. I do not expect step 6 will be needed. If you go through step 6 and it doesn't work you may need to disconnect the shift levers individually and try again. Once a device is paired, you should not have to disconnect it or remove power from it to continue the process with other devices.
If none of this works to pair your shifting system with the SC-7900, then the wireless circuitry in the shift system is defective (as I mentioned previously, this is probably in the front derailleur). Even if it is out of warranty, you may be able to get a warranty replacement since it is a newly discovered defect that could have existed from the factory. You will probably have to talk directly to the Shimano service department for this.

Try flushing out the shifter(s) with WD-40, use plenty. The next step will be replacing the shift cables and cable housings.
