Linked brakes

I don't think we've discussed this of late..

A friend of mine has just bought a Deuville as a 'returning to biking'
bike.

We were talking about it the other day and he mentioned the linked
brakes. Front lever applies front only, break pedal applies front and
back 70% - 30% apparently. As a result, he has decided to use the
pedal almost entirely.

I've never particualrly thought linked brakes to be a good idea, but
this idea that it leads someone to use the pedal as the primary brake
strikes me as dangerous: if he swaps bikes, his initial, programmes
braking response will be the back brake, after all.

What do you all reckon to this?

You have a point - when I ran Guzzis in the 1980s, I got used to just
stamping on the pedal and it took a short time to adjust when I hopped
on other bikes. But generally, you adjusted by the second corner, or set
of lights.

In short - I wouldn't worry.

 

Bloke's a ****, innhe.

<thinks>

Not Robbo, is it?

 

[snip stuff about linked brakes]

Is that because he bought a Dullsville or because he uses the pedal?

No.

Which leaves you with 30% and 70% not being used - and that 30% on the front
is potentially rather a lot when you need it.

I've only ridden one bike with linked brakes, a VFR - and they were
noticeable. However the brakes overall were the best I've had on a bike.

That said, I made full use of the front lever as opposed to using the
pedal...

I'd suggest to your mate he gets in the habit of using the lever as he's
never going to be using the brakes as well as he could <shrug>

 

....and your money's on Robbo being a thick ****?

He probably phoned a friend.

 

Well, that would definitely be worth investigating. He seemed quite
certain he had it the right way round, as described by the shop he got
it from, but never having ridden a Deuville, how should I know?

I'll get him to make sure....
I'd hate to see him crash.

Me 'Bird has that setup. I wasnt replying 'cos I was waiting for the
post of next week, but you've spoiled it now :-(

 

It does? You wanna get it looked at, sharpish.

Okay... but I can admit to being wrong... but I'm not sure how.

"applies front and back 70%-30% apparently"

Now considering my understanding of (VFR) linked brakes it's a complicated
system of variable piston usage - you pull the front, they don't all come
on - you use the pedal, even less is applied at the front.

Which means you aren't using them to full usage unless you use both and you
definitely aren't using even close to the front potential if you're just the
pedal.

What have I got wrong in this case?

 

Good point. Roughly 70/30 both ways, lucky you mentioned that before my
impending track day virgin fiasco :-(

 

They have thre, 3 piston calipers, 2 front and 1 rear.
The Front lever applies pressure to 2 pistons on the front each side
and 1 on the rear. The rear pedal applies pressure to 2 on the back
and 1 on the front each side.
As you say you need to use both brakes to get full braking effect, but
on CBS machines I usually use the front only, unless really braking
heavily.
On non CBS, I use front and back, with front harder than back.
The only bikes I can compare are Pans. 1 model has ABS, TCS & CBS, the
other, nowt, just old fashioned brakes.
The ABS ones brake better than the non, IMO.

So er, what did I get wrong?

 

Wouldn't mind a virgin fiesta, tho. Or even a virgin siesta.

 

IIRC, they're over-rated.

Give me someone who knows what they're doing, any day of the week.

 

heh. Well, yeah, sure. I've only had one virgin, and that was when I
was too, so neither of us were in a position to compare.

 

well, trust me on this one - they're nothing to write home about. On
the plus side, they don't know what's considered normal...

 

darsy says...

If ever I have a virgin writing home would be the last thing I'd to TBH.

 

Both is better.
