Hi,
I am new to this forum and also very new driving a Ducati Hypermotard SP.(previously drove BMW GS for many years!)

It is a brand new bike, only 2500km on it...

But I have some issues with it, it is the front brakes! When I brake, then I have to pull quite deep, if I release it and quickly pull the handle again, then the brakes hit very early and aggressive! Meaning that the pressure seems to increase or something... so the brake point is different (earlier and harder) the second time I pull the handle. This happens all the time...

I have been to the dealer, they have checked the possibility of air in the brake system, but negative. They are claiming it is "normal" with the HyperMotard... hmmm.. hard to believe to be honest!

Can someone else confirm this behavior or tell me this is NOT normal??? When I am driving fast thru the Austrian/German/Italians alps then I would like trusty and good brakes!!

Any help would be appreciated!

Best Regards

This is obviously not normal behavior for any brake system.

When you apply the brakes do you feel any pulsing at the lever?

The reason I ask is because a warped rotor will push the brake pads and caliper pistons back, so that upon the first application of the brakes, part of the lever movement moves the pistons back into position and the rest of the lever pull presses the pistons against the brake pads and rotor.

The caliper pistons are now in position so a second application of the brakes (soon after the first) requires less lever movement to actuate the brakes. Ride for a while and the pads and pistons are pushed away from the rotor again and the cycle repeats.

If it's not a warped rotor check for the brake pads not moving freely.

Another culprit could be a master cylinder piston that is not moving freely such that upon release the lever does not fully return to its full release position. This prevents the reservoir from completely refilling the master after each stroke. Aftermarket levers often cause problems.

Thanks for the reply! I agree does not feel right!

It does not pulsing when I apply the lever. Strange is that the dealer here in Munich says, it is "normal"... I found it strange. Never had this with my BMWs I have had. The brakes are not anything only for the hyper... it is Brembo brakes... weird.

It is a brand new bike! Nothing changed or modified!

It is not normal.

Can you notice something when braking and looking at your brake fluid reservoir?
The level of breaking oil should not change, nor should you see bubbles, ...
Try slow breaking too.

Otherwise the fill valve, seen in the figure at the right, could be somewhat defective, loose, and thus leaking now and then.
By quick pressing or ... the valve straightens or something and works.

I'm no specialist, but that would be the first thing I would look into, And it's a simple thing to check.

Hope it helps.

My 2014 Ducati Hyperstrada does the same thing. Changed pads, it helped a bit but not a fix.
Took the dealer around the showroom pulling on different brake levers. Most of the ducati's felt mushy & inconsistent, Most of the BMW's felt good. He could feel the difference but was not very interested in finding a fix for the ducati. Told him I didn't care about the warranty just tell me how or what to do to fix it. I'll paid for it. They don't know I guess. :violin:

There's a guy on another forum that had the same issue and he fixed it by installing I think Beringer master brake cylinder (I think a ted bigger one).

Found it, see post #17

Hi, I have a 2014 SP. Have you reached a solution? It sucks having to buy a replacement aftermarket master, as per comments by boki above. My front brakes do not pump up like yours, but I have to pull quite far/deep on the lever until they grab. This is consistent pull to pull and they are still powerful. I realize these brakes are meant to be progressive in feel, but I have a full 1/2in or more of travel on the leaver before they grab. This does concern me. Does anyone know if this is normal for the SP?

 

[greghubbs]

If the brakes on my Toyota were anything like my 2014 Ducati Hyperstrada brakes there would be a world wide recall.
And how about the fuel tank 7 tenths of a gal less than what the owers manual says. Mine runs out of gas after using 3.5 gal. That's missing 20% of the claimed amount [ 4.2 gal ], should be a recall on that too.

Does the bike have ABS? That seems like a few years ago and some people had issues with inconsistent braking on new bikes with ABS. If your bike isnt equipped with ABS then i would pay someone else to bleed the brakes before condemning the master cylinder. I had a bad master cylinder that would stiffen up on the second pull.

I helped a guy with the same bike, except he had a bad clutch master cylinder. Same symptom, he had to pump it up to get into gear.

I am beginning to wonder about my gas capacity also. My warning light comes on very early. Tank is 16 ltrs and reserve is 4 so I should be able to add 12 ltrs once the light comes on. I have no tried this yet or kept an eye on it. Next fill up I will see what I get.

My front brake performance is a concern. I am not sure if there is a problem. I have almost 3/4" of travel on the lever before the brakes really grab. Dealer said this is normal. This delays my response time when braking and the lever has to be set way out to prevent contact with my knuckles. This makes reach an issue.

Once they grab they are consistent but they do not seem all that powerful. I expected more from brembos x 2. I tried with the abs off and get a little more power but not that much of a difference.

I am thinking a Beringer Bro14. Does anyone have experience with this application. I am wondering if it is compatible with the ABS.

:BoomSmilie_anim:

in the manual they state 4.2gal including a reserve of 1.05, so i think that sounds about right?

I don't have that issue with mine, did you play with the dial adjuster?

Thank for the input.

Yes, its not lever play but actual piston travel in the master.

 

[theRealCrazy]

ha, sucks, could there be air in the line? Trapped air can make your brakes feel squishy or soft, did you try bleeding the brake?

Yes the dealer bled them which did help a little.

 

[theRealCrazy]

mmh.. maybe the dealer used DOT3 brake fluid, maybe get Motul's RBF600 - Racing Brake Fluid it is DOT 4 with a Higher boiling point than other DOT 3, 4 or even 5.1 of some other brands.
I know some riders use that one to race on 1099s... I don't know if the feel would be that different but it's not difficult/expensive to try it out?

Very nice. I would like to install the rcs19 but I do not think it will fit under the hand guard on the hyper 821. I do not want to remove the hand guards which also means adding new signals somehow.

Any one install an RCS 19 on a hyper 821? If yes photos would be great.

I have a Hyperstrada, all you need is the Brake line kit: EL-0102-002-710

From: Spiegler Performance Parts - Standard-Line
It banjo bolts on to your stock brake line, It's about 4" long and banjo bolts to the new master Cylinder

Just about any master Cylinder you like will work that has a 18 mm or bigger pump. the one on the Hyperstrada is 16 mm pump
