dot 4 brake fluid
« on: 04 July 2019, 16:33:53 »

Can I top up with any brand of Dot 4 or should I stick to a VW supplied fluid?

Why does it need topping up would be a fairer question...

No point putting half a litre in only to find you need to remove it again in a months time when the pads wear out completely  ::)

some people replace brake fluid as a "service item" as you'd say  :y

VW do it every two years. Q related to top up, hence my post ;)

it seems to be under the level just a tad - the guy who fixed the steering rack said there was corrosion on the brake pipes but no obvious leaks. VW have never mentioned corrosion over the years and whatever is there now must have been there at last MOT a few months ago I would have thought.

sorry - it is my eyesight - just went out and removed cap rather than just look from outside and it is on max when you prod the reservoir. looks to be on minimum at first sight.

It's possible that those pipes aren't visible normally, but it's only once every thing is stripped away to access the rack that they become apparent  ;)

I asked him whether it was worth having the underneath treated by one of those specialist companies - he did not think wire brushing would be a good idea at some of the unions. not sure whether to at least get some protection on the dodgy areas using a specialist company.

You do need to top up as pads wear and, when you have stonking multi pot calipers, it becomes necessary long before the pads are worn
