Please don't try bending back 6870, 8050, 8070, RX-815, 8150, or 8170 shifter blades. These are made of cast alloy. You have to remove it, heat it up and then bend it, otherwise they will likely to crack, or even snap. I'm working on a comparison video between 12 speed 105, Ultegra and Dura Ace. It should be out by the weekend. I will cover topic of bent shifter blades.

Excellent video. My ST-R8070 has a broken bracket which I would like to replace. But I cannot find any place where I can purchase the affected part. Can you provide me with the web site where I can purchase it? Thank you for your advice.

Which bracket are you referring to? The alloy brake lever, or Di2 shift button? Unfortunately neither can be purchased as a spare. Your only option is to find a broken 2nd hand one. Shift paddles (Di2 buttons are the same between rim R8050 and Disc R8070 shifters.

Thanks for your help. im shting the pants thinking of cutting the screw as the torx didnt work..lets see how it goes. Quick question now that we are here on the shifters. i have a 105 hydraulic (no DI2) and when i press the break, it doesnt come back to the original position. im trying to bleed (if i manage to remove the screw) but it was bled before and its relatively new. do you know what could be the causes? thanks a lot

Have a look at my ST GRX-RX815 shifter video. I'm taking apart R7020 shifter. There is a small return spring inside the master cylinder. But it's unlikely it would have snapped. However, there is small return spring that is attached to the 'push rod plate' it is held in place by a small pin. It could just drop off, from that pin, hence lack of return force.

Hi I will do, but I have a limited amount of time. This is my hobby, and my day job takes priority. I'm sure it will be out sooner than later. If your threads aren't stripped completely, a temp solution may be 12 speed bleed caps, as they are bit longer.

Yes, they are exactly the same. The only difference is the embossed model number. The only difference between R8070 and R9170 is a bar clamp and lever material (carbon on DA and Alloy on Ultegra)

@richardprice115 Have you tried bleeding the system again? I'll be posting a video with a quick fix on bike repair of the shifter. If you can wait till the weekend. Also, NEVER use metal to push Shimano brake pistons. They are made of very hard but brittle ceramic. Very easy to crack them.

Hello I have taken apart and checked bladder and reassembled but when I try to pump hydraulic oil in at the caliper it won't go in like there is a blockage.have you any idea what would cause this??
@Di2_GP
Ай бұрын
@richardprice115 I'd check, one thing at the time. First disconnect hose from the shifter, then try bleeding to see if brake fluid runs freely. If that works, the next step is to look inside the shifter port. It has a bit of white plastic, and this can be compressed/damaged. If that's also OK, the only other solution is to take the shifter apart, and blow compressed air inside the hydraulic channels.@@richardprice115

@@hallra1970 Ah, I haven't tried to repair it as I'm not confident I can do good enough repair and ensure the system will remain safe under pressure. Bleed port, repair is 'safe' as it is isolated from the pressurised system when braking. Brake hose port on the other hand is under pressure. You can try but I wouldn't risk it. Sorry I couldn't help. It may be worth looking for another shifter with stripped bleed port thread, broken lever or dead electronics.

@@hallra1970 If this is only for you, and you will test it on the rear brake, I would try Helicoil. The reason I didn't use it on bleed port was lack of space. I need to measure thread on brake hose flange bolt. Will confirm tomorrow. Good luck, and let me know how you got on.
