Stock 2023 V4R front master cylinder

Ducati Forum

Help Support Ducati Forum:

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.

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.

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.

How funny - you edited your post to remove your step by step 4-hour oil change process on a V4. 🤣 And you answered my question with a question… 🫣

You weigh the oil that’s removed and put the same back in… tricky stuff.

Your turn. How do you do an oil change on a 911? There have been a lot of models, so let’s use a simple one like a 964 as an example. Off to Google…

I don’t know why I entertain this nonsense. 🫣

What a coincidence, my brother had a 964 Cabriolet that we worked on. I agree that it’s a bit of a faff with 2 oil drain plugs and the oil filter is in a tricky spot. I’d rank the Ducati more of a faff (but only by a little) just because of the drain and refill times and the filter removal/install is also overly complicated

Because weighing oil is a great way to measure it. I call bullsh!t that your dainty hands have ever touched a wrench.

Sorry, I forgot that you think you’re an expert on everything, despite all the evidence to the contrary.

Weighing oil actually is a good way to measure it.

You’re not worth my secret sauce 😜 And if you don’t think it take 4 hrs, you’re doing it wrong

I saw what you wrote before you edited it… :rolleyes: You certainly can do it like that but there’s an easier way. No ‘special sauce’ required. And you don’t sit there watching it drain for two hours - you can do other stuff…

Still nothing on what’s involved in a 911 oil change, despite you acting like you know the difference and having an opinion on it. It’s ok though, don’t worry about it. I already knew you were spouting opinions about stuff you’ve no actual experience with. What a shocker…

Anyway, nothing you have said in the thread really has much to do with the topic, so maybe give it a rest?

Took you a while to Google that.

There’s also a vent that can be loosened to help avoid too much mess changing the filter. You won’t know about that without more extensive Googling or actually having worked on the cars. Jacking up a 911 is much more of a pain than removing one half of the standard lower fairing on the V4. There’s a lot of oil and you certainly do need to let it drain for some time if you want to do it properly. The oil level is also much harder to read (many change to a 993 dipstick as it’s easier to see the level on that one). Obviously easier to see on a V4.

The V4 is easier.
