Front brakes do not match

[dwhitehouse]

I’ve been starting to put my Z1000A1 back together over the past couple of months. I striped it down near the end of summer to get the frame painted and wheels rebuilt. I’ve just been going over the brakes and now find that the front callipers do not match . In fact I’ve got two different sized pistons on the front both a 38mm and a 43mm.

I think that a bike from 77 should have two 43mm pistons on the front, is this correct?

If so does anyone have a spare Right hand calliper in any condition (have new piston and seals) that they want to flog.

Anyone got a use for a 38mm calliper too ?

The 38mm is off an a4 the 43 is from a z1,a or b is the 38mm a right hand one if so i could use it...Thanks Paulj...

Should I not bring the caliper with me Sunday Paul ?

[PAULJAC47]

Yes Chris i still want the pair of calipers the discs and the splitter,I have more than one project on the Anvil Cheers Paul J...

What size did a1's have fitted originally ?

I'll check which side the 38mm caliper is of. Actually it probably easier if I just post a pick of it since I dunno left from right ;)

This is the one. Needs a new piston and seals:

That caliper is off a z1000 A2

Parts book is showing right and left caliper pistons for uk twin disc as being the same - 42mm

38mm showing for the A2

Just done both of mine and got the kit from www.bitzforbikes.co.uk at reasonable price

Cheers Keith.

Did they swap from 2 x 43mm pistons to 2 x 38mm pistons between A1 and A2 ? Wonder why that was.

I have two new stainless 43mm pistons and all the seals from Wemoto, just short of a caliper to fit Good prices on that web site, wish I knew about that a few months ago. Cheers for the link.

i have one of them,it was on my 900 import,could that fit what you need.i believe the front end on mine was an a1.(i stand to be corrected)

[dwhitehouse]

Thanks for the offer hillbilly but I found a 43mm caliper at Stoneleigh today. I have a spare 38mm caliper if anyone needs one now ;)
