Brembo bolts

[Pandamonium]

Hi all, it's been a long time but another V11 is back in the garage, technically belongs to my dad but it's in my garage, 2003 V11 Cafe sport with the Moto Guzzi Accessori exhausts and matching ecu, 12000 miles on it and very clean. However want to freshen up a few bolts. Does anyone know the part number for the caliper bolts as they are a bit rusty on it.

Thanks

You can also carefully clean the surface of the heads with Scotchbrite and brush on some flat silver paint if you're worried about pennies.

If you were really keen,  you could pull the bolts out and get them cadmium plated. Or paint the heads of the bolts as Phil suggested. VHT makes caliper paint in a range of colours that is heat and brake fluid resistant.

There is often the issue of them doing small jobs. Platers are used to plating mass stuff for the building industry and often struggle with Automotive standards as well. You can be lucky but it'll be cheaper to just replace them when it comes to 8 basic metric fasteners. Also you're better off not pulling those bolts out collectively. You can also by Ti bolts as well for the well healed and weight conscience and the issues with finish will be forever gone.

BTW they will be tight and the hex depth is shallow so it's easy to strip the heads out so be prepared for that and take the necessary step to alleviate that.

You got that right ! I hate these shallow head socket head and shallow head Torx. It seems like they are "one time use" and that's that. Caterpillar equipment is loaded w/the shallow head Torx and you are lucky to get 75% of them loose w/o stripping the fastener head.

Thanks for the replies. Wouldn't be too keen to paint if there are bolts out there but £41 for 8 bolts seems a bit crazy. The probolts site does give full specs including pitch and head height, so im wondering would these work, slightly taller head amd marine grade so better resistance

BTW , use a premium socket such as SnapOn to get this loose . You want to buy and use the best on something this critical

These seem to be more affordable! Remove and replace the bolts one at a time to keep from breaking the seal of the inner and outer halves of the caliper housings. Use an amount of anti-seize on the fasteners.

The issue with the std cap screw is the length of the thread. The Brembo specific bolts have a longer shank than the std 8x40 cap screw. Of course a grade 5 Titanium bolt is the best option but if you don't like 5 quid for a Brembo specific bolt then I doubt you'd spring for Ti ones.

Haven't searched through the full site to see if they have longer shanked ones yet, was just wanting to see people's opinions on them. I replaced the bolts that hold the calipers to the forks a few months back with the correct bolts from Gutsibits, they were roughly £1 each and that is why I was questioning £40

i would think the longer shank (portion w/o threads) would be to maintain caliper halves aligned.

Racebolts are always a lot more expensive than everyone else. You can buy these style bolts cheaper elsewhere but you need to do a bit of hunting them down. I provided the link as one alternative source with a quick search the "deal" is down to you guys.

belmetric.com - stainless, similar specs as Brembo - $1.05/each

Opted for the pro bolt as they are listed as brembo so should fit exactly right
