HI,
Confusion on front brake discs seems to becoming more commonplace, I will try to clarify........

All Triking Type 1 models had solid cast iron front brake discs of Triking manufacture - Cast at a local foundry and then manually machined, they are fixed to the wheel hub with 6 x 3/8 UNC bolts These discs are a unique pattern actually evolved from an odd modified Norton / Rickman motorcycle disc which just happened to be available at the time to make a pattern from. THIS DISC IS NOT A GUZZI DISC. These discs always had quality and accuracy issues due to inconsistencies in the cast iron and are now very expensive to make due to the sand / gravity casting process with a high reject rate. It is usually more cost effective to replace or modify the std T1 wheel hub and fit a T2 disc. Many Type 1models have now been converted -often as part of a wheel rebuild. A Guzzi disc will not fit a std T1 wheel hub without extensive modification and / or brake caliper re-location.
Generally if you have a T1 with early cast iron discs and they are working OK then that's great - leave them alone, If they show ANY signs of fatigue, cracking, deformation or poor surface then modify / replace the wheel hub and change to T2 discs either stainless steel or cast iron. DO NOT "skim" or re-face a T1 disc - it will be too thin for the structural integrity of the material and unsafe and / or the skimming process may reveal impurities which will result in inconsistent braking - they can crack without warning. Obviously -replace discs as a pair,

NO TRIKING T1 HAS a MOTO GUZZI FRONT BRAKE DISC as std. There were 2 maybe 3 T1s which were fitted with high performance / modified Guzzi / Brembo front discs as specials. These usually have the discs fitted with spacers and M8 bolts.

Early T2 models had the same arrangement as (T1s) above uptill around 2008.

Late T2 models (post 2008) and all T3s are fitted with a Triking stainless steel front brake disc as std. This disc is a std motorcycle disc fitted to a bespoke carrier with M6 bolts. This disc is fixed to the wheel hub with 4 x M10 socket head bolts. THIS IS NOT A GUZZI DISC A Guzzi disc will not fit. An upgrade to a high performance disc is also available this is a direct replacement for the std stainless disc but is made from rotary spun ductile iron. This is considered the ultimate in racing motorcycle brake disc material although slightly dated now it is far superior to the stainless disc in terms of feel and feedback.http://shop.trikingsportscars.co.uk/pro ... -disc-pfm/ It has the drawback of going rusty if left damp - same as the cast iron T1 discs and incidentally the brake discs on most modern cars. There were a couple of T3s built with modified Guzzi / Brembo discs as specials, these have special hubs and the discs are fitted with 6 x M8 bolts

All T4 models use a std Brembo disc which is the same as on the donor bike - fixed to the hub with 6 x M8 socket head bolts. THIS IS (effectively) A GUZZI DISC ! and can be taken from a donor bike such as Stelvio, Norge, Breva, Sport, Griso, some late California models, and also Aprillia, Ducati, etc. A high performance version of this disc is available http://shop.trikingsportscars.co.uk/pro ... rake-disc/

of course they may be the odd kit build which has been adapted or converted to Guzzi discs which the above will not apply to ! - (I,m sure someone will correct me)>>>>>>>>>>>>>>>>>>>>>!!

Bonsoir,
Merci pour vos explications,
Actuellement, un disque présente un voile de 0,3mm relevé au comparateur . Cette légèrement déformation est ressentie à la pédale lors du freinage.
Il me reste à poser la question du coût de cette remise à niveau.
Encore merci
Cordialement
Dom

The modifications to the std T1 hub to accept the later std type disc cost around £60 per hub. Or new hubs are available from £100 each this has the added advantage of being machined to accept a screw in hub cap. Both these options give the choice of the later std stainless disc or the high performance iron version.

Merci Alan
Il faut que je trouve en France un atelier qui soit capable de me changer le moyeu et refaire le rayonnage des roues.
Dans cette nouvelle configuration est il possible de passer à des étriers double pistons???
Merci pour votre réponse et vos éclaircissements sur la question
Dom

From Dom: Thanks Alan
I have to find a workshop in France which is capable of changing my hub and redoing the wheel shelving.
In this new configuration is it possible to switch to double piston calipers ???
Thank you for your answer and your clarification on the question.
Dom
