Hi all

 

Can someone confirm the correct bleeding sequence for a 1993 italian job Mini for me please? i think it has the type 4 master cyilinder but i have misplaced my Haynes manual.

 

Cheers

Neil

Not sure on the exact recommended sequence, but personally I always do it like this :

 

1. drivers side front

2. passenger side front

3 drivers side rear

4. passenger side rear

 

My reasoning for this is that the front drivers side is the shortest run to the caliper, so that way you get most air from the master cylinder out quickly. Then moving on to the passenger side front, you get the remaining air out of the long pipe run to that side.

 

Once you are at the back drivers side, you will be getting the air from the long pipe run to the back and then the short run to the side (drivers side rear is a little shorter run from the T piece). Then lastly at the passenger rear you get the air out of that final run from T piece to that side.

 

That's my view, works for me - see what others say.

 

As for MC type, dunno exactly what all the different type are but certainly it should be front to back split on a car that age.

Passenger rear,
Drivers rear,
Passenger front,
Drivers front,

Do it like this ( its in haynes)

Also dont let the resevoir run dry :)

I thought my way was different to the Haynes, but hey ho what can I tell you, it works fine my way too!

what Cal844 has said, do the rears first then the fronts due to where the master cylinder sits and the bias valve

Each to thier own i suppose!

You usually start from furtherst from the master cylinder, anyhow both ways will work as long as the system has not run out of fluid at the rear circuit.

Both sequences are in Haynes, it depends on your brake set up (servo or no servo)

I was used to the method cal844 mentions:
Passenger rear,
Drivers rear,
Passenger front,
Drivers front,

But this is for cars without a servo.

After getting a spongy pedal I looked through the Haynes manual and found that if your car has a servo it's the method spiguy describes:
1. drivers side front
2. passenger side front
3 drivers side rear
4. passenger side rear

You're both right, hand bags down!

Usually start at the one furthest from the m/c and work your way to the closest. Same with all the cars and motorbikes I've had. It probably works in other ways too. Master Cylinder bleed valves are a god send on some of the systems I have bled.

ha ha.. no handbags were out!  This is a civil forum for adults you know   (sometimes...) Anyway, I kinda knew my way was 'wrong' though maybe it now turns out it isn't really wrong.. result!

Once you've got a decent pedal it's worth finding a way of pressing the pedal and leaving it pressed overnight then give it a quick rebleed. This gives all the tiny bubbles time to group together and rise to the highest point. A couple of good presses on the pedal in the morning then bleed each nipple off a little bit more can improve the pedal
