Title: correct brake bleed sequence 99 pre facelift
Post by: rcaws on 21 August 2007, 14:45:08
Guys

Had a look at the maintinance guide, it says that the brakes must be bled in that order for pre 98 cars. Is it the same for a 99 pre facelift?

also should i bleed the clutch before or after the brakes?

Thanks

Rich

No real sequence required as its a 4 way setup....I normaly do the rear first simply because they are the longer runs

Clutch needs draining and then idealy should have the fluid forced through from the gearbox end, modifying an easibleed makes this pretty easy

Thanks.

Was going to try the reverse bleed procedure......

but have just picked myself up a pressure bleed kit, which basically uses the pressure from a spare wheel to force the fluid through, eliminating the need for pressing pedals.

would this work on the clutch as well (it says it should in the instructions) and my understanding is that the problem with bleeding the clutch the 'conventional' way is air getting trapped in the vertical pipe down from the reservoir. would a pressure kit such as this eliminate this problem??

as always help apreciated, just want to get it right first time if poss!!

Pressure bleed will work on the clutch but you have to do it the way Mark-DTM has said, in reverse so you push the fluid into the resovoir rather than out of it. So you need to attach your pressure bleed onto the clutch bleed nipple. HTH.

Grrrrrrrrrrrrrrrrrrrrr

right then. All done but.........

Got to the os front caliper, and couldnt find the bleed nipple. closer inspection reveals that at some point in the past it has been sheared off by some moron leaving whats left flush with the caliper body.

So i have 3 nicely bled calipers and one not.  >:( pedal is much firmer with more bite, and it doesnt pull to either side (which i thought it might) so seems like its ok for now, but its obviously not good to have one which still has old fluid in. Do i leave it for now and worry about replacing the caliper untill its time to change the fluid again or should i move it to the top of the '2 do list' ?

Also bled the clutch as suggested resulting in a much lighter and smoother pedal  :) but it still sits high, a good 2cm higher than the brake pedal. are they all like this?

Thanks

Sounds like you have had an interesting, if frustrating, day.   ;)

I would think about sourcing a replacement caliper from one of the cars being broken on here.  That way you can be confident that all fluid is new and little risk of it boiling if the old stuff is left in the caliper with the duff nipple.

Hmmm could say that! i might try getting whats left of the nipple out, but i suspect it will be easier to just replace the whole thing  :(

Notice you have the same as me how does your clutch pedal sit?

Its about an inch above the brake but to be honest, I never actually look, just lift the leg and there it is!  Will pop out and confirm.....

Yup, inch to inch and half above the brake pedal...

Mark - could you expand on that please?  How do you drain the clutch and where is the clutch bleed nipple exactly?

Cheers,
