I have experience in correcting the stock setup. All it took was some good brake fluid and proper bleeding technique. Easy as. Cost me $50 and 15 minutes of my time.

Sorry to hear that your lever is flaccid...

That long? I hope you are better at bleeding brakes than you are at putting stickers on your bike. 🫣

Do you even know how to bleed brakes? Have you ever bled your brakes on your V4? I'd bet not.

Which V4?

Yes, I do know how to bleed brakes. I was doing it over 35 years ago on bikes and cars and I’ve done it with various interesting cars in the intervening years before coming back to bikes. Basic maintenance isn’t really that difficult from what I’ve seen so far. As an example, the oil change on the V4 is far simpler than on a 911. Bleeding brakes on a 911 is also far more complex.

Clearly you find stickers more challenging. :rolleyes:

You do talk some utter nonsense. Are you finished yet or do you have more trolling to do before bedtime?

Seen or done? Do you have practical experience bleeding a V4 brake? It’s an easy question. What spanners are needed? What kind of tubing do you need? What’s the volume of the system? If you did actually do this, you wouldn’t be aimlessly going down a rabbit hole of a new brake setup before you’ve even ridden the bike.

If you need help with stickers, talk to your butt buddy andy. He has plenty of practical experience with putting stickers on his fugazi bike.
 
I was getting used to the stock master. Then I went and rode my 1098. So the 16/21 is kinda squishy. But if the PR 18/19 (1098) is pretty firm with 34 mm (M50) calipers it would seem it would be wooden when used on 30's. I'll stick it on anyway. It seems they never made a PR 17/?. at least I can't find one.
 
second the brake fluid upgrade, I use this

Much easier to modulate brake pressure for some reason
 
Great to see the endless pop up, I have some cans left from the 911 cup! Was thinking it was not good for the bikes. Will put it in for the season.
 
I'm not sure the wrinkly decal was caused by brake fluid. You may be able to use it to remove said decal. I struggle with anyone's ability to tell the difference between varieties of FRESH brake fluid. We could do a blind (blinded to what you're using anything else might not work out) brake fluid comparison. Like with wine tasting. Don't swallow. I think what everyone feels is some fluids age better when they're repetitively heated. If you have one that you know works you should be able to spec compare to other fluids.

the trick to best bleeding is to have comfortable easy to plug equipment, as you want to bleed V4 quite often, once in 2 days.

a long hose with a good connector that can fix to a nipple + bottle and a spanner is all you need.
 
Yeah these do seem to need to be bled alot. I tie it off after every ride, tap the calipers and let it sit overnight. And between fluid changes regularly clean the reservoir out and refill it with fresh fluid. Mixing via brownian motion. I'm thinking everybodies issue ultimately stems from the ABS. Ain't perfect as delivered for sure but this issue was so far down my list that I'm just starting to look for a solution. I'm hoping the PR 18/19 works as you don't need to change anything else.

This definitely proves you’ve never changed the oil on your V4

Explain how you think it proves that? It’s certainly not based on any first-hand experience you’ve had.

Actually, don’t bother. It’s like arguing with a small child and I shouldn’t let myself get sucked into your incessant trolling, yet here we are again.

It’s rare that your contributions to a thread are positive or constructive and this thread is certainly not one of those rare occasions. I don’t really see what you get out of it. I guess you get some kick out of derailing threads with your inane ramblings. It’s become quite boring.

Considering that the ABS unit is nestled in between the engine and front headers, I’m not surprised the fluid goes bad quicker than normal. Most ABS units are put in the rear subframe away from heat sources. Not Ducati… Though the engineers probably found that putting it in the rear subframe was hotter than the its current location. At least there’d be a little air flow where it’s at now.
