961 - No Rear Brake

Hi all,

Ist ride this year on my 2017 961 and when applying the rear brake nothing happened, the pedal bottoms out and absolutely no brake effect.

I had a spongy brake which was sorted at the 1st service, this was put down to air in the system from intial build, apparently it was a known issue because the brake pipes go up in to the ABS module under the seat and sometimes air gets trapped. Anyway before it was laid up last year the rear brake was fine, now i have no rear brake.

Before attempting this (as there is no Norton Service available at the moment) i need to know if i will get any ABS issues after bleeding the rear brake as i remember the Norton technician said the ABS had to be reset (presumably by software). The ABS is the Continental system.

The bike has only just over a 1000 miles on the clock.

Can anyone give me any advice please ?

Kind regards,

Ian

On my 2017 961, I have suffered no back brake twice - the second time was after winter layup last year. My dealer Teasdales said the upside down rear Brembo caliper on Aprilias also suffer from this - I think the factory are aware of the problem - may be due to the proximity of the ABS brake pipes to the exhaust & affecting the brake fluid. They replaced the fluid with Motul RBF 600 Synthetic DOT4 racing fluid. Seemed to work OK last year (just over 2k miles, but haven't yet been out on the bike this year - will let you know what happens.

The factory now seem to be taking parts orders & booking in for servicing so you could also contact them.

I don't think it needs ABS reset - no mention of it in the Euro4 manual, which reads like a non- ABS system regarding fluid change - you could drop a message on the Access Norton board to confirm or contact the factory

Thanks Alan,

Sounds like a plan. Have a good weekend and stay safe.

Kind regards,

Ian

My 2019 916 sport came out of winter storage & was exactly the same. It was serviced last week by Krazy Horse ( who are great by the way) and they all do it - it just needs bleeding.

Ian, maybe a good idea to join the American forum AccessNorton. They have a lot more info on the Donington Nortons
