Brake fluid capacity

[burton]

Hi,

Can find out about most fluid capacities but none about the brake fluid.

Can anyone help? How much should I buy if I am going flush the whole system.

Less than you would imagine. Less than 4 litres, probably 2 from my last brake job - although, sealed containers will last for life. It will be in the manual pdf guides.

Is the brake fluid on these cars linked to the clutch?

Says 1 litre.... Might get another litre to be on the safe side!

Is the brake fluid on these cars linked to the clutch?

Yes. All models are hydraulic clutches. They are generally gravity bled - though you really don't want to go down this route. Keep the reservoir topped off while bleeding either brakes or clutch.

Sorry for the stupid questions, but when bleeding the brakes do I need to touch the clutch or will it just be ok? I am putting in DOT4 but its blue, helps with seeing whats new and old when changing.

Just want to get everything striaght in my head before I start.

Hmm. Bleed the brakes in the correct order. Use only Renault spec fluid. I'm not sure what this is: there will be a technical bulletin or a service manual spec.

The clutch is supplied with the same fluid. Getting it wrong might mean replacing the slave cylinder which is difficult (removing the transmission)

Have found the doc referring to both but neither mention that you have to bleed both when doing the other.

The fluid I am going to use is DOT4 but is blue with better boiling points. Docs only say not to use DOT5

Alex has raised a point specifically about DOT 5. You should read it - I don't have it to hand, but there are various grades that are not acceptable. From memory the DOT 5 is to be avoided - apparently DOT 5.1 is somehow better. Vague I know. Sorry, but good luck. Bleeding the brakes is not difficult provided you have read the sequence, have common sense, and do not let the master cylinder go to low.
