Hi

Got some promax disc brakes on a hybrid that I bought 2nd hand recently.
I'm struggling to get them seated properly, especially on the near side where I'm not sure how far to move the pad in or out from the calliper with an allen key. Pads are knackered too and I'm not confident of either setting or keeping them.
So I'm wondering if I could get some cheap mechanical brakes for my work hybrid, no downhill antics, so thought I'd ask in the MTB forum as you guys will know your callipers,pads and rotors like the back of your hand, I hope :D .

Seen some Clarks DMB-8 which are cheap and cheerful, any good?? at £17:99 at CRC for a calliper and rotor I'm not expecting F1 braking but will they be OK for a 12 mile round trip commute on roads 3 times a week??

Got a marin muirwoods that has promax mechanical brakes at present

Also, can I but any size Rotor as there are 160's and 180's.

thanks
