Thanks for that. They were originally planning some kind of Castrol fluid, just checking which one they were going to use.
I think that was the one they were planning on using. Happy to pay the extra for something like brakes. But by regular changes, how often do you mean?
Depends on the usage tbf, but at least every trackday but if its doing more road milage i found it needed done even more often
Assuming one only changes the fluid and doesn't remove any brake system components, shouldn't the system stay air free while flushing it if you never allow the fluid level to drop much in the fluid tank? I'm also thinking whether or not I need to fab up some pressure equipment to change the fluid. My plan is to change fluid (been overlooked for a long time) and test the brakes without removing calipers to see how much they return to normal functionality and pedal feel with only the fluid changed. Once I start stripping the system down then I'm sure to need some special equipment regarding the ABS pump.
You really need to get it to a garage and they can plug it in, so the abs valves can be operated while bleeding, or else some old fluid stays in the system.
^Well that's obviously true, but it shouldn't be a large amount, should it? And as far of air goes, no air should enter if tank is kept full while flushing.. But of course air could also enter from the bleed nipples if one is not careful when operating them when bleeding the system.
many reports of people messing this up,and driving around with spongy brakes. Meganes just seem to be tricky to bleed pro pally without doing it by the book. I have always left it to my Renault tech mate,who has the relevant equipment to open up the ABS valves.
^might have to invest in that RSTuner tool from Fastchip sooner than later then, as it will allow operating the ABS pump via OBD + software with the correct module. These modern cars are way too complicated... Gotta shell up for all kinds of special tools just to do basic things. But that's how it goes ofc.
Just my findings Endless - easy best all round performance Castrol srf - v good performance plus comes in 1L container Motul rbf 660 - v good but heat cycle’s out before Endless (excellent in road car) Something to be aware of with mk3 Megane, if you drain brake fluid down to lowest level in reservoir with view of filling with new fluid you run risk of allowing air into the shit design clutch take off pipe which is situated half way down side of reservoir but out of sight.
yep..quite a few people do this.. Wait to you have to change the oil. I have already told you the fun and joy to be had on the 225!
on a mk2 on the floor it aint! filter way up ,hard to get removal tool on ,and conveniently dumps oil all over the subframe when filter is removed.
Sounds like an ingenious design by Renault once again. I don't suppose there would be room enough fit a funnel of sorts to collect the oil spill when removing the filter?
i suppose so..the gap between rad and filter is very narrow. undoing the filter,while offering up the funnel will be the tricky part. Would be far simpler on a ramp no-doubt.
