Over a period of about a month, I went through every lining on the market in the front of the Mach 3. The test was - up Dyers Pass to the Sign of the Kiwi and back down to work in Colombo St - hard. If I had a front brake left after that it was suitable for racing.
Only one lining ever managed it - an American Raybestos industrial lining - probably solid asbestos...
I remember you writing about that one as used on the maniporri cableway.
Those arent the ones you have though are they? as they would have had top mounted mudguard.
ps they were on the list although only i thought they were only imports
One i did leave off the list was TZ250 only one model though i think, around 86 or so maybe. Also maybe likely a TZ125 or two as well I am not that familar with a lot of Yamaha stuff.
I missed this with all the background Jap Yap noise...
I eventually found some new Ferodo ones and took them down to the Brake Shop, he looked at them and dismissed them as "too thin", so after some searching pulled a set of rears off my shelf T110 as the pre unit rears are same as half width 7" ones.
Dropped them off and await the result.
I initially pulled the front apart as I thought the wheels bearings were knackered but turns out the DIY axle spacer is a few thou less than the 20mm wheel bearing. Surprised that Triumph wheel bearings are metric.
DeMyer's Laws - an argument that consists primarily of rambling quotes isn't worth bothering with.
They were probably supposed to be imperial,but with 3rd world production tolerances
Don't you look at my accountant.
He's the only one I've got.
Interesting i had a countershaft seal fail when my son had a CRF50
I ordered the seal twice the second time I confirmed the fiche number myself neither seal fitted as they were clearly to small on the od
Afterwards on the third fail i went to the local spares shop it turns out the seal was imperial rather than the metric size the parts fiche said.
I wondered at the time if Honda had subcontracted the CRF engines out to the Chinese?
I recall many years ago when I was an apprentice and for 6 months I was working with a guy who was big into vintage cars.
He told me a story about early Ford bearings only being available from Ford as they were a special size.
Turns out they were metric.
Did a Google search today whilst on the train into Auckland that you helped pay for, and turns out a lot of bearings were metric even 100 years ago.
Nice relaxed trip from Penrose to Britomart, one less vehicle on the road and I can text, read, update to my hearts content and only $3.50.
Probably have a beer on way home so can drink and ride and text.

TZ250 84/85 were mounts for 300mm disc side mount mudguard, and 40mm. 86-88 were same but 320mm disc mount (mounts both sides, 86-87 had one 320mm disc, the 88 had twin282mm discs and adaptor plates to make the calipers fit). 89 stayed 40mm, went to new sliders for 282mm discs an cartridge dampening internals. ALL are incredibly short only about 695mm long. They are also bloody expensive to buy and only two other bikes I know have 40mm forks. Vmax and GPZ1000RX!!!
40mm forks
40 Kawasaki KZ-1000E1/E2 "ST/Shaft" (79-80)
40 Kawasaki ZX-1000A1/A2 "Ninja" (86-87)
40 Yamaha VMX-12 N/NC/S/SC/U/UC/W/WC/A/AC/B/BC/D/DC (85-92)
40 Yamaha XVZ-12 DL/DKC2 "Venture Royale" (84)
40 Yamaha XVZ-12 DN "Venture Royale" (85)
40 Yamaha XVZ-13 T/TC/U/UC "Venture" (87-88),
40 Yamaha XVZ-13 DS/DSC/DT/DTC/DU/DUC/DW/DWC "Venture Royale" (86-89)
40 Yamaha XVZ-13 DA/DAC/DB/DBC/DD/DDCDE/DEC "Venture Royale" (90-93)
I missed the Seca 2 and the diversion that had 320mm discs as well
