Reviews of Castrol DOT 4 brake fluid (1litre)

Great DOT4 brake fluid at an excellent price. I bought 2x litres but only required 1 but, I now intend to flush my BMWR1200GS brakes along with the wonderfully complex ABS pump every year, so it won't go to waste as it's sealed. Great service as always from Nippy Norman's...

Service my brakes every year and oil looks to be in good condition when changing. So always use Castro as never have a problem and all Castro product are excellent quality, nippy Normals has a great selection at great prices and arrives quickly.

Same as BMW, but cheaper. Good stuff at great prices.

I've always stuck to castrol when it comes to brake fluid and use this across all my cars/motorbikes. It seems to be priced similar to any other not known brand so it's a no-brainer.
