Shimano recall road mechanical disc callipers

As the crowds flock to see the new hydraulic Shimano units there's issues with the mechanical ones

On the first day of Eurobike, when Shimano will be hoping that their new hydraulic road discs will be one of the big draws, it's a touch embarrasing for them that they've also had to issue a recall for their mechanical road disc callipers: BR-CX75, BR-R515 and BR-R315.

"Shimano has identified a potential performance issue with these brake calipers", says the recall. "So far, no injuries are reported. As a responsible company where the safety of our customers has top priority, Shimano is voluntarily recalling the brake calipers concerned. Shimano is replacing these with improved brake calipers in which the issue no longer exists."

So it's not clear from the recall exactly what the issue is – and everyone we could ask for more details is busy setting up at Eurobike – but it seems to be something to do with the calliper adjustment. "Readjustment of worn brake pads in the case of the brake calipers concerned should be performed by the bicycle dealer. However, it cannot be excluded that consumers and dealers will adjust the brake pads incorrectly. This can lead to that the braking force is being more difficult to control and brake performance can be influenced."

If you have a bike that's affected, or you're not sure, head over to your local Shimano dealer to have your callipers checked out.

Great start to a disc brake equipped Euro Bike

Wasn't an issue like just coming with the race to force the road market onto disc brakes. All the cycle press amd media are constanly banging on about is that the future is disc brakes. What are the legal implications of Shimano insisting that brakes must be adjusted bt a Shimano dealer. So does every bike shop have staff trained by shimano?

Call me old fashion by I will stick with simple and basic caplier brakes. Been out to my local hill climb tonight and braked from 44mph to a stop at the bottom of the course well inside 100 yards on Record brakes and Mavic exalith rims. Which I adjusted before my ride in 20 seconds. So if I had Shimano disc brakes I would have to take the bike to my local shop at 6.15pm on a Tuesday night. I think not.

So I just can't wait to convert all my bikes to discs and I have the perfect the excuse to say I just cant get on my bike enough.

Good on Shimano for having the balls to issue a recall instead of hushing it up. Toyota has a similar approach in the car world. However, I'm slightly concerned by the implication that only "bicycle dealers" should be able to adjust brakes... let's not forget that a bicycle is a fundamentally simple machine and I'd hate to get away from the situation where everything is user-servicable providing they have the right tools.

Wow that's a lucky thing - I just finished rebuilding my MTB and decided to buy a little used set of Avid BB7's c/w levers off ebay, but before I spotted them I was going to buy some Shimano mechanicals instead - good thing I checked ebay out and made a sensible sniper bid.
