Moderate update: brakie brakie
Been aquiring and researching tiny parts to get the SRP brakes and Kooka brake levers back together. Had to wait on lost orders and just general wait times for things to arrive. Yesterday in the mail I received some very much needed NOS Kooka Racha foams from @Star12 . Mahalo dude!
As you can see in the photos, one was torn. They go on about as hard a putting grips on bars. Tight mo-fo’s! The other brake lever foam is still intact so will set aside the other NOS brake foam for a rainy day.
Additionally with the Kooka brake levers, the anodizing process is quite aggressive to ferric and brass metals The brake levers originally have a brass pivot with a 2.8 mm ID hole that a steel pin slides through to mate the lever to the cage body. The anodization process didn’t fair well at the beginning so the constant and prolonged submursion in the solution ate the original brass pivot right out of the brake lever. Thanks to @Dr Dremel and his link some pages back for a company located in Germany who sells all sorts of bushings from all kinds of materials in virtually any practical dimensions. I ordered spares and a few different sizes, just in case. These pivot bushings dropped right in and everything is nice and smooth. Thanks dude!
Next up, the SRP brakes. Also over exposed to anodization solution which ate away the helicoils for the brake cable clamp down bolts. Went from m5 threading to somewhere close to a m6! No worries. Ordered titanium m6 bolts, then chased the threads with m6. All is good. No difference in weight. Though I need to figure out a pinch washer solution. You know, the little washer that sits between the bolt and body of the brake arm and pinches down the brake cable. I need to fix that.
