I’m looking for the original or new caliper bolts for my 1993 Monster. They were changed some years ago to new stainless ones but they are not correct, the head is far too deep compared to the ones in the picture. If I am to buy new and have plated any suggestions on which quality to buy, worried I’ll buy the wrong type from eBay.. picture below for reference not from my bike.
I would give Pro Bolt a call https://www.pro-bolt.com/ Previously I have found them very knowledgeable If something isn’t immediately in their catalogue then they can usually fabricate it in your choice of material
Thanks Trying to find the low profile head type is a challenge tbh. And not sure what stainless would be suitable..
This is what mine look like below, clearly the wrong head size. I’m looking for original bolts or new aftermarket but have to be the correct low profile head. I can always have them plated yellow if needs be… The mounting bolts are the wrong had size too…
Have a look on the Accu fasteners site. Top quality, certification on some fasteners etc. A proper engineering supplies business. They’re one of the best suppliers I’ve used in years.
Not off hand, but most fasteners tend to follow DIN or BS standards. A low profile cap head, will be the same. I don’t think the ones Brembo used were anything special or bespoke.
I refurbished my 916 calipers in the summer, here’s a few photos which may help identify the bolts - I had mine zinc & gold passivate coated by JW Rudge in Birmingham. As mentioned above by Sev, they are marked with 8.8 and also an R.
Accu list a 5mm head depth in 316 grade stainless steel. They also list a 10.9 HTS. Just need to check the shoulder length.
I think I have an original set of these that you can have if you cover postage. Will take a look tomorrow. From memory they have already been re-plated too. Fingers crossed.
Head depth is 5mm. I purchased stainless ones a couple of years back, but they couldn't be torqued to spec..ended up with titanium ones.
Well, good and not so good news. I have 8 bolts, all freshly re-plated. One unfortunately was seized in and I had to resort to a torx bit to get it out. If you want them they are yours gratis. Simply PM me your details. FYI I now remember I replaced them with stainless bolts, exactly the same size from Westfield Fasteners. I also had these yellow passivate plated which until then I was unaware you could do with stainless (but you can).
