Caliper identification ???

[wents75]

Hi again

Hi
Ok this has been bugging me for some time. My 550M has this single right side caliper with only a short banjo stem. Some iv seen definitely have a taller one. Did these vary? As metioned I believe its 1975 M
Any thoughts guys.
Ta Ian

Just found this info from an ebay seller.
https://www.ebay.com/p/Suzuki-GT-250-Gt ... 2120745382

made the discovery that this part will only fit 1973 models GT250,380,550,750
1973 they had a shaped brake line screwed into the top of the caliper. ( such as this )
1974-77 They had a banjo bolt which is a different / large size... and is taller so that the brake line can approach from the side (photo 6)

Maybe that's it Iv got a 73 Caliper.

I have exactly the same problem. Bought a supposedly 76A model caliper off Twowheelspares on ebay which I sent for refurbishing without looking at it to be told it's only suitable for a 73 bike.
Trying to get them to take it back for a refund at the moment.

Thats annoying seeing as you where mis sold it.

T'aint like the one on my 550K when I bought it.
That had a thin metal pipe that went horizontally from just behind the fork leg to the caliper, but bent down above the caliper and entered the caliper vertically down with a compression type fitting holding the swaged pipe end onto a raised casting in the caliper.

I'll find some pics when I get back home.

If alan is refering to the pipe on the green (black) meanie 550K I replaced it I believe its in the shed some where colin

No, I changed that caliper as the old one was in really poor condition.

It's surprising that there were so many variants. I've got a couple of odd balls in my collection.

There y'go. Now whether this is the correct one for the US market K model (this particular bike was built in August 1972 according to the 'vin' label) and must have been one of the first ones built as we only got the J model in August '72 (I bought what was described to me as one of the first sold to the public), goodness knows.

Yeah
Thats like the one on my ebay link above if you view the + 2 pictures.
I got concerned about the replacement service kit but Deans at Discount bike spares run through all the years.
