Brembo rectangular reservoir pedantry

[the lodger]

Mine seem to be the same size visually . When you say larger , do you mean obviously larger or is it fractions of a millimeter ?

Can you tell me the part number for the correct set ?

Many thanks

If you absolutely, positively have to have the original wording, then Stein-Dinse appear to have them.

Edit: The full Brembo part number is 110430860 (another example here) https://www.ebay.co.uk/itm/BREMBO-PS...-/351990583876

The bigger ones are significantly bigger.

I think there are some crossed wires here?
I think all the lids are the same size and not even handed from what I remember. (Although there is a front and back.)
However the actual pots do come in different sizes (heights). The early brake reservoir was the same size as the clutch, but this was enlarged fairly early on. I am fairly sure that there are two different piston sizes for the brake master too. (not that it's an issue here).
Certainly the single disc models use a 12.7 or 13mm piston and the twin disc version is bigger but I can't remember the size atm! I believe the single disc reservoirs stayed the small size for a while but were later increased to the same size as the twin disc one, with just the piston sizes differing.

Watch out for Scrambler brake masters (They use a cable clutch) as they use "coffin" reservoirs with a 13mm piston, but I think the design is different to the Monster era Coffins and I don't think they interchange.

Strange that the lids with DOT 3+5 seem to be saying use Glycol OR Silicone based fluids... That can't be right??

Nope. I’ve had both and the lids aren’t interchangeable.
Early coffins are the same size lid as the clutch, whereas later 90s coffins are bigger.

If you take your lid off, make a note of the Brembo seriel no. Cast into the underside.

Fair Dinkum Darkness.
I have a box of all sorts and I thought that I had mixed lids and masters with no problems, but I will have another little play when I get a chance and see if I have two sizes of lid.
I've only ever seen DOT4 lids though.
