    Posted: 28 Oct 2019 at 17:25
having just bought a V50 1979 and reading the various posts on the front brake performance.

I have tried deglazing pads and discs etc - but have just found a place in Wales that is going to reline my spare pads with a different compound with a different coefficient of friction - a softer pad with greater stopping power with the same mechanical effort from the master cylinder.

after discussion with the very helpful chap there - I will let you know the outcome.

the rear brake is fine - and the combined braking is fine - just nice to have a slightly better front on its own.

Be very interesting to hear the result.

The brake performance is whatever was considered adequate in the 1970's LOL

Update on pads.
I posted them yesterday -monday -and rang them to check they'd arrived today Tuesday safely.
They'd arrived and they were being worked on and just had a call from them to say they'd been posted back to me .
1 day turn round,  wow.
They've fitted some woven high coefficient of friction,  softer material to them m which , according to them , will give better braking for the same mechanical effort.
Yes , they may wear quicker , but we'll worry about that later , given my usage.
Let them bed in and see what happens.

Sounds like a good result, and if you find the balance of the brakes has been altered, do you have the choice of adjusting the balance or putting similar pads in the rear?

My only problem with linked brakes was on steep downhill gravelly stuff, where just the rear would have been preferable.

In an emergency stop, I imagine the balance could be critical ...

Yes interesting indeed.
Personally I like a reasonably decent front brake .
I know I can balance the overall effect with the foot brake

But frankly a tremendously helpful chap  who was willing to listen and suggest things

If you have a v50 2 with the front master cylinder under the petrol tank that will be an issue...substitute a conventional handle bar mounted one.And maybe try softer pads....be very careful about pad/disc material compatibility or you'll be looking for new discs soon.

Actually just moving the M/C from under the tank won't really help and could make it worse. There is a slight mechanical advantage on the operating lever on the M/C under the tank and you lose that on the handlebar.
You really need to source a smaller diameter M/C.
Softer pads of course, is what this topic is all about.

well - just had them back - pronto service and helpful over the telephone - posted Monday , back in my hand today.
 
he has bonded some "woven" material onto the original pad backplate for me.
 
apparently (and I asked him specifically) not aggressive to the disc at all - but the pad will (understandably) wear quicker - how quicker , time will tell.
 
£10 by the way = --- let you know how things go -- when it stops raining of course!!

10 pounds will do one set of pads on my solar cycle, so that sounds pretty good as they are the size of postage stamps.

And my new Spanish keyboard has a dollar sign, and a Euro sign ...
But no pound sign.
Does it know something I don't?

well - been out on the V50 round the block the long way to the MOT this morning.

I was a tad concerned on the % braking efficiency of the front brake as the pads were new , but rode the long way there.
need not have bothered as the % rear was 32% and the front was 30% - a pass in anyone's book.

the off side disc has cleaned up nicely but the lever feels spongy as you'd expect really until the new pads settle - but for sure they re no worse than the original ones that came out.

time will tell

Don't know if it works with Guzzis Richard, but when my BMW brake got a bit spongy, I would lash it to the handlebar with elastic overnight. Order was always restored.

Sorry to hear about the back Dave, been there and done that too many times.
Been sleeping in a hammock for three years now, beds give me backache.
Take it easy ...
