LCR Brake/Brembo bleed sequence??

[JONNYVT]

Hello

Gonna try to improve my brakes by chn=anging the fluid to some quality DOT 5.1 stuff.

Will use my trustee Gunson EZEE BLEED and the usual method of caliper furthest away caliper to closest to the MC method (rear ns, rear os, front ns then front os)

QUESTION: The Brembos have 2 bleed nipples, does it matter whcih I do first (front or back) or do they have to be done together (possible but tricky)?

Not found anything on search for this

Do inside then outside

remember the clutch is on the same system so do that too!!

Remember there are 9 bleed nipples in total: each front caliper x 2, each rear caliper x 1, Master Cylinder x 2 & clutch x 1.

THe basic rule of thumb is like bleeding radiators, you start with the furthest one away and work back to the MC.

There was a good thread on uk-mkivs.net recently about the problems a couple of people were having with porsche/brembo calipers, worth a read.

The rear calipers are quite a poor design and tend to hold air even after pressure bleeding, it's worth giving them a light tap or 2 (when bleeding)with a rubber headed mallet to dislodge air bubbles.

Also, correctly adjusted hand brake cables can firm up the pedal a little.

On the fronts i normally do the outside nippe, then inside, As for sequence its N/S, O/S back & front.

yeah me too....no problem with bleeding breaks as ive done it before, have not got the facilities to pressure bleed but i am in the process of making a cylinder to pressurise the master cylinder, will this be ok and where are the bleed nipples for the master cylinder and for the clutch!? where do these fit into the sequence of bleeding?

 

[D_O_U_G_I_E]

Yeah, l'm looking to do this next week too...so any help/info on the situation would be gratefully received!

Did we manage to find out where the Master Cylinder nipples and clutch nipple is?

Did mine two weekends back and used the gunsons eezibleed(tyre at 15psi) which worked well. Sequence I used was rear drivers, rear psg, front dr then front psg doing brembos inner then outer nipples. I opened each side for a few seconds then closed and repeated quite a few times till i noticed the change in fluid colour, the new stuff was much more transparent and i think this equates to 0.2 litres each corner.

Clutch slave nipple is poking out on top of the gearbox right in front of the gear change arm that attaches to the gear cables. its a pain in the ass to do without removing any other components but still do able with a stuby spanner. I didnt do the master cylinders as i couldnt see the point but id imagine they are under the resevoir so need the restricting pipes removed.

When i did mine i didn't bother with the clutch ones, this is only required if you loose all the oil from the system, but as i was only changing the oil i left it , this was about 6 months ago and all is well. Also you dont need to bleed the brakes when changing Disc's or pads.

Subscribing out of interest, is it right the recommended service interval on a brake fluid flush is two years?

 

[vwbassett]

Yep, recommended is every two years. Those who hit the track/race generally do it more often than that as once the fluids out the sealed container its properties of being uncompressable start to deteriorate as it takes on air/moisture which is why you shouldnt keep an opened bottle on the garage shelf too long.

remember the clutch is on the same system so do that too!!

I changed mine the other day done the rears then fronts (ouside 1st), left the clutch alone and havent had a problem

 

[Mark300zx]

I don't think it causes a problem not bleeding the clutch, it gives a more thorough job, ensuring as much of the old fluid is bled out of the system.
