Ultegra Brifter: Play in Break Lever
I have a fairly new bike with the Ultegra triple group. I have ridden
around 1500 miles. I noticed today that the rear brake lever has some play. Around 1/8" measured at the top lever opening and probably a 1/4" plus if measured at the end of the lever. The brake cable is tight and no movement of the cable occurs during this initial lever travel. The front lever does not have any play in the brake lever. Is there something to be tightened in the lever to remove the play? The levers are Ultegra Flight Deck from 2002. Thanks, Dave Patnaude |

Ultegra Brifter: Play in Break Lever
David- I have a fairly new bike with the Ultegra triple group. I have ridden
around 1500 miles. I noticed today that the rear brake lever has some play. Around 1/8" measured at the top lever opening and probably a 1/4" plus if measured at the end of the lever. The brake cable is tight and no movement of the cable occurs during this initial lever travel. The front lever does not have any play in the brake lever. BRBR May need to unwrap the tape from that side, cut off the tape holding the brake housing to the bar, then 'seat' the housing end into the lever by squeezing a few times, then re-taping the housing, adjust the brake.

Ultegra Brifter: Play in Break Lever
David- If the housing is firmly in place with tape to the bar and then the
handlebar tape over that, I wouldn't think that this would be an issue making the lever have play. The housing should only be providing alignment for the cable and not affecting lever or cable tension? BRBR Housing needs to be seated into the lever. If the housing is secure(but not seated) and the first time the lever is squeezed, the lever will have a wee bit of play before moving the cable.

It seems like it was ok. I pushed it in harder and it seemed to help, but a full squeeze of the brake lever and it was back to having some play. I found that the rear brake seems to be not returning to its full open position which is causing the tiny bit of slack. The caliper needs a little push to fully open and make the lever tight. The rear brake is Shimano 105 with the Ultegra lever. Any further suggestions to resolve this problem? Thanks, Dave |

BRBR Either adjust the caliper(loosen the bolt that you see on the front of the caliper, on the right side) or pull trhe spring out of it's little slot, bend it up a wee bit and put it back into the slot.

Ultegra Brifter: Play in Break Lever
Peter's suggestion is quite good, and there are a couple of other
things you need to look at also. Grab the QR end of the longer brake arm and see if it wiggles fore/aft. If it does, the caliper likely isn't the problem. The trouble you've got is often caused by excess cable drag somewhere in the run from the shifter to the caliper. The front housing piece should be cut so that the bars will turn all the way right without pulling the cable. A little longer than that is OK, but not much. Rear piece should have a nice smooth curve from housing stop to caliper. Lengths in general should be as short as possible while allowing the bars to reach the "full-lock" position. Sharp bends in housing tend to be sources of drag. If the housing has developed a crimp at the ferrule that could also be the source of your problem. Pull off the ferrules and look in the ends of the housing for occlusion by untrimmed ends of the metal winding that is the body of the housing. If you find them, they need to be trimmed, and the housing end finished with a file. Have you made sure that the cable is lubed inside the housing? I use white lightning for this, as it's thin enough to run all the way down the housing with the bike turned up. Have fun, Eamon David Patnaude wrote in message ...
