Sirion M100 rear brakes


Hi Guys,

I need to service my rear brakes, I think they are out of round so I’ll probably need new drums, shoes, cylinder. I don’t want to spend that money on new replacement parts when I could get a good upgrade for similar money.
Are there any good bolt on upgrades for the back of the sirion 2000 m100?


no bolt on option’s as far as i know.


Thanks for taking the time to reply, I thought that might be the case. All my searches for sirion brake showed up putting sirion hardware on other cars.


yeh sirion brakes fit L200 and L500 mira’s and L600 moves. Oh there maybe one option for bolt on but I honestly dont know if it is an upgrade or just the same. Copen brakes would also fit but I really dont know if you would get much better performance out of the drum brakes if they are a touch bigger.


I looked at some listings, looks like the Copen are the smaller of the 2 drum sizes for the sirion. Apparently the sirion has either 180x25 and 180x35.
I think I’ll just order the parts for replament oem. I ahven’t even looked yet to see if I have the 25mm or the 35mm, maybe if i have the 25mm I can upgrade to 35mm.


I think it is the best plan :slight_smile:


Use the rear drums from a GTVi sirion


GTVi shoes seem to be the same size, whats the difference in the drums?
