'16 Speed Triple Front Brake Issue (Brembo)

Hello all, my Speed Triple has developed a condition where the front brake must be pumped once for a solid response. To be clear, there is a 1/2 inch (or more) difference between the first pull of the brake and a second pump. Further, it doesn't stay pumped... every time I apply the brakes, I have to do a double pump. Really frustrating, as the system has been bled countless times to no avail, master cylinder replaced under warranty (no difference) and most recently ABS pump replacement (no difference). Any ideas as to what else would cause this to happen?

I have a ‘16 as well and I’ve noticed that double pump difference actually today.
I’ve been overseas for 9 days and upon return I picked up the bike at the airport’s lot, the lever went down almost touching the grip, second pump was almost normal, maybe half way and third one was normal.
This tells me that this may be normal operation if it’s happening to other bikes, especially with the indirect ABS box. As per my mechanic, brakes with ABS will feel not as sharp but more “progressive” as you squeeze.
I remember my 2010’s brakes were way more responsive than these fancy-pants system. I guess it’s all about having ABS nowadays.
I just ordered a racing-grade brembo fluid with hardness higher than 5.1 fluids and brembo brake pads also racing grade which operate at cold temps too. I still have some of the old pads left to wear so I’ll report when I replace those parts.
There’s not really much more you can do since you bled the system assuming that the fluid you’ve used was from a new, sealed bottle that’s is.

Thanks for the comparison. Check out a new speed triple in the showroom. I've tried several and none do this. All work was done under warranty by a factory mechanic. They are stumped, as are the techs at Triumph. I'd think that if this is a development, rather than an existing-from-new issue, something is off. I ride in the city every day and the double-pump thing is getting a bit old. Yeah man, please let me know what results you get, will follow the thread.

Yup! Now that I've gotten some proper seat time on my '17 S3, there is definitely a lot more "play" in the front brake lever vs my previous S3's. I'm with Nicspeed as to the reason why; ABS. On mine, it seems the brake lever firms up nicely the harder you brake. These are really great brakes too.

You got loud pipes, but you ain't sayin' nothing!

Traded my 16 for a 19 recently. The issues you have are the same as my 16.
I had Pazzo levers and on low setting could pull them to the hand grip.
Made several claims to dealer who didn’t do anything to resolve.
It actually improved a little on its own after 15,000 miles????
Last resort was to purchase Brembo pads but never got around to install before trading for the 19S version.
Still have the pads if anyone is interested.

Damm and I JUST got a set that arrived yesterday. Did you post them in classifieds? I would’ve taken them given they are suitable for street and not just racing.

I'm new to motorcycles maintenance but the first thing that comes to mind in a car is improper bleeding (which still might be the case - mechanics are notorious for being wrong). For example my mechanic bled my system on my car three times before I had him switch which brake was bled first, aND bingo! Problem solved. I know it was a car, but still same concept.

Second is I'd guess there is water in the line. Maybe the cap in the reservoir was improperly sealed and allowed moisture in.

Next I'd say the master cylinder is going bad, one of the internal pressure plates or whatever. Also maybe a bad piston in the calipers.

Just my guess here lol.

FYI my '19 S has no soft brake issue like your describing.

Thanks. Same here. Pazzos touch the grip at low setting. There is no way this is ok. Still under warranty, so hoping it can be somehow sorted. Really not cool having to double-pump every time I brake.
So far, the lines have been bled multiple times (by dealer), new master cylinder and new ABS pump. No improvement. Back to the drawing board and def not comfortable with accepting this as a "characteristic" of a $13K machine.
