Been sold old Brake Fluid?
Discussion
Doing my bike with dot4. Bought some brake fluid from amazon. As a test I poured some into a clean plastic box and it comes out yellow. I'm sure when I first bought my bike it looked almost clear. I looked on the bottle it came in and it says 29 sep 2021 but is that the expiry date of manufacturer date ? This stuff (brandless I guess) calls itself "Comma".
Should I send it back or carry on with the fluid change?
Many thanks in advance for anyone more experienced than me to take the time to answer.

Brake fluid is normally an apple juice or golden syrup colour. I expect the date on the bottle is the date of manufacture- I doubt they’d print an expiry date on it. If the bottle was sealed then it’s good to use.
ETA: check that DOT4 is the right stuff for the bike if the current fluid is a very different colour.

Light amber/yellow for new DOT4 is normal.
ETA. Just checked another make of DOT4 I've got in the garage & that's amber.
Funnily enough I have got an old empty bottle of Comma DOT4 & the small print on that says the expiry date is 3 years from the date of manufacture - I'm guessing that your date is the date of manufacture.

Brandless?? Calls itself Comma?? Should I send it back or carry on with the fluid change?

You mean Comma, the manufacturer of OEM approved lubricants and fluids for vehicles??
The mind boggles sometimes
A quick Google suggests Comma Dot 4 is 'Yellow Orange' in colour: http://www.cdgltd.co.uk/files/ww/coshh/BF4ESP-L.pd...

I was thinking much the same. Comma products (from "Wash'n'Wax through oil to brake fluid) have an entire aisle in my local motor factors.You mean Comma, the manufacturer of OEM approved lubricants and fluids for vehicles??

My only complaint about them is that everything they supply comes in the same type of bottle, so you have to be careful not to put antifreeze in the oil and wash the car with brake fluid.....
