CB500/550 / Comstar brake shoes
« on: April 05, 2024, 07:33:51 PM »
Hello all
Went to change the chain and sprockets and found that one of the brake shoes had separated in the rear drum when I took the wheel off. Gotta love restoring bikes!
Anyway, the CB550F2 I’m working on has Comstar wheels on (don’t burn me, it came with them). The wheel size is showing MT 2.15x18 and N 18xMT2.15 878 DOT. The Shoes have H-283 on them.
It seems there are many different variants of this Comstar wheel so the brake setup is different across the range.
I can’t find any brake shoes listed with H-283.
At motorcycleproducts.co.uk they have quite a good search system by model etc.
If I’m measuring them correctly the shoes are 160mmx30mm (if I’m interpreting the guidance on the website correctly)
If I search by size 160 x 30, these look the closest but fitment says MZ. https://www.motorcycleproducts.co.uk/160mm-x-30mm-brake-shoes-001951/1/001951
If I go up to 160 x 40 these look spot on visually and the figment suggestions match a more plausible batch of bikes that would have likely been candidates for the wheel swap out with this 550 back in the day, but I don’t know if they’ll be ok at 10mm wider https://www.motorcycleproducts.co.uk/160mm-x-40mm-brake-shoes/1/001953?bike=10127_71
I wouldn’t be surprised if the previous owner skimped and put in the wrong size.
Can anyone here throw any light on what I should go for?
I’ve got more photos if it helps.
Many thanks
