bleeding brakes, soda stream brake fluid

Ohright, the blanking screws I took off had old washers around them so I just made new ones with ptfe.

Did think about it but wasn't sure how ptfe would react to brake fluid.


Does anyone know for sure which way is "off" for the load sensing valve on the underside of the car? I want to make sure mine isn't goosed.

Got mine free'd up yesterday and all callipers bled The bottom bit should be hard against the rubber bit on the body, basically push the bottom of the lever towards the valve to fully open it, my spring fell of so just stayed there, but you may have to clamp it off. If unsure Ill take some pics, cars still on stands atm

Just looked at mine then and it moves with my fingers now, so push the bottom towards the front of the car- thats open

Bottom of the lever towards the front of the car is open. Gotcha.

I'll prob's do this at the weekend. I forsee swearing, spanner throwing and general tantrums.

My mate, and long time dubber, is adamant that I've knobbed up bleeding the brakes But he has a spare brake bias valve too if I need it

lol. Probably something simple, it'll make sense when you got the rear passenger side jacked up pretty high, can get ya head under and can see what I mean, try spray some wd40 on it before trying to free it, i just whacked mine with a hammer after a while lol can move it with my fingers now!

Yeah it moves freely I just wasn't sure which way was open. It will be something simple I hope, just running out things to replace or eliminate.

Right I reckon this is a weird noise for brakes to make. Any suggestions?

Engine is running.

hmm ive noticed this noise when bleeding my old mk2's but not as loud.

Is the servo vacume hose in good shape? no air leaks?

Did you mess with the servo at all?

Leaking fluid anywhere?

tbh mk2 brakes are a b!tch to bleed at times. When I upgraded to 280 with the 8v master cylinder it was a long and pointless job!

You just have to keep bleeding the system till the pedal is firm.

[Neo Badness]

Checked the vacuum hoses the other day, they seem to be in good order. It was also pointed out that if there was a leak then pedal would be harder and the car would be running rough as it'd be drawing extra air through the servo. It's not doing that.

I do have 280mm brakes but with a 16v 22mm M/c. Did buy, I think, and S2 23mm M/c. But can I find it? Can I f**k... Anyway, I reckon it'll just be a case of bleeding it, a lot.

Meant to add bleeding brakes with the ignition off or on? I've been doing it with the ignition on but the engine off. Could this be part of the problem? Going to try it with the ignition off see if that improves matters.

[Mr Blue]

shouldnt matter. I bled mine with the enging running. Takes a while
