DOT 4 Brake Fluid

This stuff from Halfords is about 4 times cheaper than the DOT 4 stuff from bike shops:

Is it the same? Is the stuff from bike shops any different or just a rip off?

I don't understand why bike specific fluid is so expensive. Do the just prey on people's ignorance, thinking they need bike branded products?

Yep.

And a bottle with a pretty label....

The only possible good reason to buy a small bottle of bike brake fluid is that you may never get through a big bottle! (unless you have a car too!)
Or to reduce the risk of contamination as you are always told with cars to be cautious once the bottle is open as any contamination may cause to brake failure....... :shock:

Oh hell yes

You do actually get slight differences between different dot 4s- different endurance, and different dry and wet boiling points. But it's nothing you're ever likely to know about on a bike, and there's no guarantee that the expensive bike stuff is any better than the cheap halfords stuff in the black bottle.
