Rear Drum Compatibility


#1

Hello Brain Trust,

Does anyone know if the new Copen (LA440K) rear drums are the same as the early model Copen (L880k) and/or the same as Sirion/Storia (M101) rear drums?

I can’t imagine Daihatsu re-inventing a number of different rear drum brake specs, so presume they’re all the same…there are some finned covers for the LA440K rear drums. Wondering if these are backwards compatible to a Sirion to retain drum rears - but add some extra cooling.

The 2005 Copen are showing up with a 180 mm X 38 mm shoe, can find a listing for the LA440K

Uuuuu, arrrhhh. Are they alu with a cast lining. I put 240z alu drums on my Datsun 1600 and they had iron lining shrunk fit inside. Would be nice and light.

I’m not really sure - so much is in Japanese and/or translated to english.
