Trust the guru... Cheers kb......

Kin stupid size anyway. ... I'll have a look for you tomorrow Paul.
 
Are so,....dont forget these are not radial mounted calipers.
Rear bolts are M8x20mm.I think its standard thread pitch,....although I cant be sure,....sorry.

Thanks for rear calliper spec. Agreed axial bolts are shorter... 20mm sounds v-short though... looks like I'm going to have to get my Vernier Calipers out after all... :)
- Front calliper spec I obtained came from Pro Bolt expressly for their Tuono 2002 - 2005 spec Calliper Mount Bolts... although they don't publish this on the website.

Any reason to believe rear mount bolts will not be same pitch as the front mount bolts (i.e. 1.25mm in this case)?
- When I spoke with Paul @ Powerhouse (Caliper specialists) earlier this week he thought the rear was M8 but didn't mention anything re different pitch front Vs rear.
 
M10 x 40mm 1.25mm FINE PITCH A2 STAINLESS SOCKET CAP



M8 x 35mm 1.25mm FINE PITCH A2 STAINLESS STEEL SOCKET CAP




Best i can do at the moment, if you want them trimming............... up to you pal
 
Just bung some washers under the head,,,,,,,,,,,,,,,,,,,sorted.
 
exactly, and maybe a tumble dryer under the back uns..
:lol

Garry,

Appreciate the offer (and everyone's feedback above)... and thanks for the effort to post pictures.

I prefer the 'standard' look (minus the tumble dryer :) )... and save you the effort of turning them down... so will source std hex bolts in s/s, thanks.

For completeness, I can confirm front/rear Calliper mount bolt specs (for 2002 - 2005 model with standard Brembo Goldline Axial mounted callipers) as follows:

- Front calliper Mount Bolts: M10 x35mm x (1.25mm pitch)
- Rear calliper: M8 x20 x (1.25mm pitch).

Thinking of going A2 grade stainless steel. I note pro-bolt claim A4 (316A Marine grade) is better for non-corrosion, and although not as strong as A2 the difference is negligible in terms of suitability.

Has anyone seen corrosion occur on an A2 grade s/s bolt?

- Bolts... man... bolts... never knew they could be so much fun...! ;)
 
:) Mind you... all the road salt these days... and it may as well be a boat! ;)

Actually... Pro Bolt only sell A4 grade s/s (Marine Grade)... so I'll prob buy elsewhere as A2 is significantly cheaper... unless anyone advises A2 will eventually rust(??)... in which case makes more sense to go for A3 or A4.

NB: Not all stainless steel is rustproof... as my Longlife Exhaust on my old Saab 9000 proved. It lasted 10yrs... and was still going strong... but wasn't a pretty sight! Pro Bolt recon A2 will 'corrode'... but not sure what that means in practice.

I know what you mean the one on my Alfa is exactly the same
 
I'd just buy normal Stainless ones and if they went manky a few years down the line.....Chuck some new ones on again :)

Mind you each to their own, that's why other Tuono's look nicer than mine lol
 
Job done (sort of!).

Replaced front and rear calliper mount bolts. Hex originals came out easy due to Copper Grease having been applied. Replaced with A2 stainless and already looks 10 times better than the rusting originals.

... but couldn't remove calliper punch bolts. First the cheap carbon steel m5 Allen Key socket started to twist. Then using Crome Van m5 bit hex bolt head started to distort. So decided to postpone the operation. I was warned that is a common problem with older pinch bolts. Calliper rebuild specialists often drill the heads off, take calliper halves apart, then remaining stud can be unscrewed by hand. Not planning to do a full calliper disassembly at the mo, so will wait for the next service and supply the bolts instead.
 
Another Tuono rider who used to drive a Saab... must be the stonking acceleration thing ;)

Interesting observation & good to know...

Re. Stonking acceleration.
I reckon so:
...plus... loads of torque, solid/reliable aircraft engineering (i.e. Saab & Rotax), easy to work on, upgrade, etc, plus individual style...
Not to mention Saab owners are typically sensible... intelligent... cerebral... erm... plus car suits bigger/taller chaps...

And Fugly has an Alfa... Another great car with some similar traits... and lots of character. I was certainly tempted by a Alfa Sud Cloverleaf in bygones and a 166 in more recent years.

:thumbup
 
I had a Saab,,,,,,,,loved it but I'm not bigger nor taller.
 
Old 'classic' 900's were very thirsty, even worst than a Tuono (but then twice the engine size and 8x the weight, so Tunos are Worse! ;) ). Mind you, Saab did for the 1850cc engines what Triumph couldn't do, in making them reliable! That said, a good condition classic is now worth more than when it was new...

I had 9000 auto, which gave between 30 and 40mpg, so not bad. The performance of a 900T or tuned 9000 (300 bhp +) more than made up for the economy, bit like a Tuono too. :thumbup

Then there is the Saab high mileage forum. Some cars running well above 500k miles, and going strong... Mine had 200k on it when I sold it, and timing chain was original and fine. And only used 1/4 L of oil in 12k miles. Loved it, but the Tuono is certainly more fun even if not quite as safe!! 9000's were found to be 30% safer than their nearest rival (Volvo), and 50% safer than the average large family car, according to Sweden's largest insurance company stats.

The newer GM variants weren't so impressive though, and I'm sure there was more than one rogue 100% Saab car produced as Gary's experience implies... ;)
