Twin leading shoe

Forums

Hello

I would like to add a twin leading shoe set up to my 650ss. Has anybody got any experience of using Norvil product ? This seems considerably cheaper than RGM however maybe this is for a reason ! I would prefer to use original but not so easy to find.any advice would be appreciated.

Do they both have the internal stiffening plate?  You might not be comparing the same product.  The plate inside links the outer ends of the shoe pivot pins and prevents them from flexing.  I think you can buy them without, which seems to defeat the objective of improving brakes.

The cheapest solution would be to get a used Commando TLS brake-plate complete and then fit the stiffening kit if you require it.  I use one on my Mercury without the add-ons and it is a big improvement on the original Dommie SLS brake in that it doesn't fade on a hot run.  Cold braking is also a little better but that could be the lining material.   Cheers, Howard

I know the Norvil one is offered with a choice of with or without the stiffening plate. If you wanted to keep the look more standard they also do a TLS without the airscoop.

Hi all,

I was waiting for a TLS front brake to come up for sale in the various internet web sites and Classic bike mags - but they seem as rare as hen's teeth! 

After 2 close shaves regarding cars pulling out on me, I decided to bite the bullet and ordered a new TLS brake hub from Norvil, complete with all the bells and whistles.

Not surprisingly this gave an immediate improvement, and has continued to improve as the miles rack-up. Much recommended!

I also changed the brake lever from 11/8" pivot to 7/8" , another step forward in braking efficiency - much needed on some of the 1-in-3 banks here on the North Yorks Moors.

I now have much greater confidence in the machines ability to avoid errant car drivers - priceless!

best regards,

Chas

I use a Commando tls brake plate with a stiffening plate in my Wideline/650ss hybrid, and as Chas said, set up correctly it improves with use, as the linings bed in. I also use 7/8" pivot-centre levers; which also improved my clutch pull no end over the 1 1/8" ones!

How do I change the pivot-centre distance? It's not as easy as only changing the lever. Also the lever mounting should be changed because they should match.

You can find them at auto- jumbles as I always take a ruler with me to check the centres at 7/8 and not the 1 1/8 ones as there are far more of the I 1/8 centres than the 7/8 centres. If the levers have adjusters on them they are normally of the1 1/8 centres.

Hello Chas,

Have you had any experience of holding the motorcycle on the front TLS brake whilst facing uphill i.e. when neither of the shoes will be giving a self-servo action.

Some of those hills are indeed very steep and I have managed to warp brake drums going down them despite going in a low gear and trying to keep the brakes cool (and failing to do so).

Fritz,

Be aware that on some of the levers sold nowadays, the 'heel' of the main part next to the clamp does not go right back to the handlebar. The stress from heavy braking can therefore cause a fracture to occur. Difficult to see if made properly from pictures if you are buying online.

Morning All,

In response to Richard's comment re- TLS holding on steep hills. No real experience of this (as yet) . Seems to hold ok on moderate hills - at the traffic lights on Prospect Hill in Whitby for example (for anyone familiar with the area!) About 1 in 10 ,at it's steepest , (for those who are unfamiliar).

The rear brake is good enough to hold by itself on most occasions.

best regards,

Chas

The place where I always worry is going up Rosedale Bank round the lefthand hairpin. I find it essential to use the centre or right hand side of the road and dread finding oncoming traffic forcing me to move left, or to stop. So I wondered what a stop would be like with a TWS; I was thinking of fitting one to a V.......e!

OK, I could avoid that particular hill, but I like the ride. I suppose I could limit myself to a reverse run with a TLS which would be great going down the Bank, and with the added benefit of being on the less steep outside of the bend!

Richard

PS Need to be able to hold on the front brake alone in circumstances where you wish to select neutral for a while.

PPS You would probably be right if you think that I'm making a mountain out of a molehill !

Morning Richard.

Coincidentally, I had a potential chance to try out the brake on Chimney Bank in Rosedale last year. Following an elderly gent in a car up the bank when he stalled on the apex of the right hand hairpin bend. Luckily he had given advanced warning that he was not a confident (competent?) driver as I had been following him for some miles and I was hanging well back. I was able to swing out and overtake as the road was clear.

As the slope is about 1 in 3 at the point I was much relieved that I did not need to stop or restart!!

I think you have a valid point, but for 99%+ of riding the TLS brake wins hands down.

My unreserved recommendation would be to go for the TLS. The brake I bought was from Norvil and the quality is superb, though the price is a bit salty.

Best regards,

Chas
