SRAM Rival brakes
HI I have a Scott road bike with SRAM rival calliper brakes. The metal components - nuts / screws etc are corroded and therefore I either want to to replace the components or get new brake assemblies. Given the lack of parts at the moment, if I can't get the rival calliper brakes, are the SRAM Apex brakes compatible? If anyone has pointers around sourcing the nuts / screws etc then Im all ears on that as well

It's just that disc brakes do have a caliper - eg. https://www.deporvillage.net/sram-force-22force-1-hdr-flat-mount-fr-complete-brake-caliper?country=GB&gclid=Cj0KCQjwrsGCBhD1ARIsALILBYrIGo4lT7YGjygG_0Qu7paH1IOvPNp95mPOFlY5DFUGDqInRmDivvMaAp_LEALw_wcB
Pull ratios may differ slightly between manufacturers, but the brakes will still operate.
Just be wary about using a different brand's caliper as it may well use Mineral Oil instead of the Dot 5.1 fluid that SRAM brakes use.
Also you'll probably need to do a brake bleed once you fit a new hydro caliper.
Alternatively Brasso metal polish or similar can work well. If they are pitted or not even stainless results may vary.
don't bother soaking bolts, etc. just take off those you can/are happy with with the brake still being safe and take to local nut and bolt man who will sell you replacements for pennies.
If only things were so simple!
Your "local nut and bolt man" will almost certainly only stock marine grade (soft) A2-A4 bolts. These aren't the same grade as the caliper ones and could easily snap. A M5 bolt ( same size as the cable clamp bolt) in marine grade can only be torqued to a safe MAX of 4.6NM ie not enough. A2-A4 bolts are fine for things like bottle cages but I wouldn't use them on a brake caliper .
go to the man who supplies the trade, not b&q/local hardware shop, ask for what you want and he will supply it.
not sure where you get your stuff.
rubbish.

Just because you can't understand it, doesn't make it rubbish.
As to where I get my stuff, thankfully not the same place as you.
I need to replace my saddle rail clamp bolts as the Titanium ones are knackered on my FSA seatpost.
These would be easy to find.
Many bike bolts are martensitic stainless steel which can be hardened and are much stronger. They are magnetic whereas A2 A4 aren't- if you need to check a bolt. These stainless steels are 400 series but will be more difficult to source. They also aren't as corrosion resistant as marine grade but more so than steel.
Making (evermore) lightweight parts calls for small diameter bolts, that's why a hardened stainless bolt is often used.
the guy who supplies my bolts supplies motorbike and car bolts
if his bolts stop my and everyone else's motorbikes at 180 mph they will stop a bicycle.
stop over complicating this.
go to the bolt factor. its their job.
i honestly, honestly give up.
are ti bolts ok by the way?
