Just received a letter in the mail for rear brake recall. I have a 2019 supersport. Did you at any time before this happened, feel that your rear brake felt squishy?

That’s a characteristic for the Tech to test associated with Recall instructions… and, the replacement brake lines are less resistant to pressure related problems.

I’m stripping it down on Saturday... the piston rod is lubed as a matter of course... so really don’t know what the cause is. The worrying this is that the pads on the rear have all broken up, so I think that a bit of the pad has jammed in between the disc and caliper causing it overheat and lock up. As I say, I rarely use the back, so wasn’t riding the rear brake...

I did adjust the lever by means of undoing the nut and lengthening the rod into the master to get a feel on the back brake a few weeks back because as standard the lever went right down with no effect...maybe Ducati really slacken it off as a matter of course as it didn’t work at all.....

I’ll get images for you and post them up before I strip it down.

Sin, is it possible that the pad broke apart and jammed against the caliper? I remember going for a long weekend trip on my V11 Sport Guzzi and the right front caliper was shedding brake dust the entire trip, luckily no heat. Somehow the pad was crooked and the leading edge of the pad had it's front corner ground down against the rotor. I have no idea how or why the pad got crooked. The brakes worked find and didnt fail but I had a mess of brake dust. We didn't figure it out until we got home. That was about 1500 mile trip.

It is John... that’s the only conclusion I can come up with.

There’s your problem. You can’t extend that rod much before it prevents the cylinder from completely cycling each time you press the brake… causing the caliper to incrementally tighten on the rotor… then bad things happen.

..and a little bit of poo came out my bottom.

went for a blast out yesterday with some mates, on it a bit on the twisties when sudden,y the rear brake locked up! the rear was squirming round but managed to keep it shiney side up.

I eventually came to a stop in the middle of the road, and how cars behind me didn’t slam me up the arse I’ll never know....
Rear wheel was stuck solid, so had to drag the bike to the side of the road. Rear disc glowing red, and caliper red got...so pissed on it. Waited for it to cool down and eventually freed. The ABS sensor wire was melted through the sheath, and the pads are bolloxed, so need to order new ones. They are all broken up with some chunks out of them. I never use the rear brake, unless on icy roads or steep hills, so the only conclusion I’ve come to is that part of the pad has got in between the disk and caliper and locked up or the brake was somehow stuck on ever so slightly..

Anyway, I’ll strip it down and order new pads etc...

I had something similar happen at about 45mph. Kept it upright and was only about 5 miles from home. Once it cooled down, I was able to limp it home. Happened again about .5 miles from home, but I was only doing about 15-20mph this time and expecting it. Took it to the shop and Ducati IS taking care of it for me. The reasoning for mine was because the Termi slip-on is too close to the brake line and boiled the fluid. What I don't get is that I was able to put about 1700 miles on the bike AFTER the brake warranty work WAS DONE. They are putting extra heat shielding around the brake line, but flat out tell me that it's a good possibility
that it will happen again. I don't know what the heck to do. If I ride it, will it happen again? I'd have a REAL hard time selling it in good faith...??

@Tail light removal Welcome! Very glad you joined us! Please introduce yourself (e.g. other motorcycles, riding experience, etc) in the New Member section.

This was a recall item...was the recall done on your motorcycle before this incident occurred? (We don’t have any recorded incidents so far of this happening again after the recall work was done.)

Sorry, was trying to figure out how to update my profile. Anyway, this did happen ~1700 miles AFTER the recall. The blame has been pointed to the Termi header pipe being too close to the brake line. The line was herniated as well.

 

[Ed K]

@Tail light removal Oh wow, sorry to hear this; yours is the first incidence of this happening after the recall work was done. Who installed the Termi?

I had the rear brake lock on last spring. I was on the motorway and after about 30 miles the bike didn't feel the same. We came off at a long slip road and I rolled off the throttle and thought the bike had Loads of engine braking. Came to a stop at the roundabout and when I went to pull away I stalled the bike. It wouldn't move, the rear wheel was locked solid. Luckily I was with my dad who managed to get people to pull around the bike which was in the middle of the road. We managed to move it after a while to the side of the road. Luckily he was on a Honda which had a great tool kit under the seat. We let some fluid out from the caliper and I Rode the rest of the day without touching the brake. The brake has never been any good to be honest so no idea how it happened. To get it to work you need to pump it a couple of times before using it, it just about passed its MOT. now I barely ever use it in case it locks up again.

@Doggy Was the recall done on your motorcycle, too (or a later model SuperSport)?

I have no idea, I bought the bike last year. It was five years old but had done minimal mileage, 1,545. Its now on 6k miles , with a big road trip coming this year.

@Doggy Not sure if this Ducati-recall-check link will work for motorcycles in the UK, but might be worth a try.

OK, thanks very much, I will do.
