Clutch Master Cylinder.

OK OK I know I'm mechanically impaired but I have brake fluid welling on the floor. After replacing the brake fluid reservoir cap which was split I still have brake fluid flowing down the onto the steering wheel boot then onto the floor. Minor but never the less annoying.
Question 1. Is the brake reservoir both for brake and clutch?
Question 2. Is that the master cylinder directly under the brake fluid reservoir
Question 3. I believe I may have to replace the master cylinder and or slave cylinder. What exactly is it I need to buy.
Question 4. I have looked in the forum links page and most parts suppliers are o/s. After my shock horror of $60 for the cap from Burwin Motors has anybody any suggestions for spare parts. I seem to remember members mentioning a German spare parts dealer, would that be Syncro-Services?

Michael,

The reservoir is combined clutch/brake.  The clutch cylinder is fed from the common reservoir and is otherwise unconnected with the braking system.  Your leak could be from the reservoir or it could be from the brake master cylinder, which is also fed from the common reservoir.  If it is the reservoir, it could be a leaking connector pipe or it could be an age crack in the (plastic) reservoir.

If it is the brake master cylinder leaking, it might be just seals.  Seals should be available as VAG spares.  It can also be that the bore of the master cylinder is damaged or corroded.  Most master cylinders can be honed smooth.  This is work done every day by brake specialists.     

In the event that you need to replace the reservoir or the brake master cylinder, they are identical to the two wheel drive T3, so this greatly increases your chances of getting one second hand.  Try Lloyd Davies, Volkspower and Volkscare., but this should be fixable without replacement of the major components.

                        The brake master cylinder is a bit inboard of the reservoir and lower down.

                        You have to determine if it is the reservoir or the brake master cylinder – see above.

                        It should be fixable locally with a minimum of spare parts.

The brake and the clutch master cylinder are available cheaply in Australia. I wouldn't bother with seals.

Many thanks. I'm a bit clearer. My mechanic in Pambula whom I think is OK (he fixed the overheating problem) suggest not to go down the secondhand path to replace the old cylinder unit. He suggest that I buy the unit and he will fit and bleed if necessary. Is there a difference between master cylinder and slave cylinder?

If it turns out to be the reservoir thats leaking,do I need to bleed the system after emptying the reservoir and replacing?
 
Thanks

Michael

Work out what you need and order it from Tooley's @ Waitara. They will ship it to you.

Michael,

Phill says that new replacements are inexpensive, so that is the better path.

The master cylinder is the one that drives the slave cylinders.  The master cylinder is connected to the brake pedal.  The pedal operates the master cylinder (assisted by the booster), which pumps hydraulic fluid to the slave cylinders, which directly operate the brake shoes (rear) and calliper pads (front).

It is possible to change a reservoir without having to bleed but it needs an expert.  The safe course is to bleed.

Wolfsburg is in Geelong but they post anywhere in Australia .

Michael, you may need to remove the instrument cluster to inspect the brake master cyl.
If you can see fluid running down the bottom half of the booster from the base of the master cylinder than replace the master cylinder. If it is dry up top and the two bolts that hold the clutch master cylinder  are wet and dripping onto the steering boot replace the clutch master. Brake fluid is corrosive, so make sure you clean up the brake fluid and wash the surfaces. Greg E

From the inspections I have done I  think it is the latter, the clutch master. Tends to be dry up top but those two bolts at the bottom, just at the top of the pedals, are where I see the first signs of fluid. Does this mean I only need to supply the Clutch Master Cylinder?

Phil .
Yes I do have a disk, but this is beyond my expertise, I will get the local mechanic at Pambula to do the job. It's just that he see's a convenience for him and a cost saving for me to arrange the parts. Any idea of price Phil for these cylinders if I decide to replace both as an future insurance whilst at it?

I think it is around $100 for the clutch master cylinder.

Print the page off for your mechanic.

I don't know how close your dollars are to US ones..
but $ 60 for a brake res cap is obscene ..
if that's anything like 60 US.
 
Both brake and clutch master cylinders are under the instrument cluster and above the pedals.
stick you head up under by the clutch pedal see if the clutch master cylinder rubber boot is wet or leaking.....shouldn't be any fluid there of course.
 
yes, the Res on top of the Brake MC is for both clutch and brakes..
there's that line going off on the side of the res for the clutch hydraulics.
 
to know what to buy , identify the problem exactly first .........is what I always recommend.
So many people try to do it the other way around ..
guess at  part first, then take it apart, then find out what you really need.
 
time for some good 'inspection and diagnosis' ..
then order the right parts.

OK OK I know I'm mechanically impaired but I have brake fluid welling on the floor. After replacing the brake fluid reservoir cap which was split I still have brake fluid flowing down the onto the steering wheel boot then onto the floor. Minor but never the less annoying.
Question 1. Is the brake reservoir both for brake and clutch?
Question 2. Is that the master cylinder directly under the brake fluid reservoir
Question 3. I believe I may have to replace the master cylinder and or slave cylinder. What exactly is it I need to buy.
Question 4. I have looked in the forum links page and most parts suppliers are o/s. After my shock horror of $60 for the cap from Burwin Motors has anybody any suggestions for spare parts. I seem to remember members mentioning a German spare parts dealer, would that be Syncro-Services?


it's very unlikely the resevoir is cracked , or the res itself is leaking.
In thousands of T3's I've worked on ..
there's never been one cracked or leaking Brake fluid resevoir ...
and sure ...a used one would be all right ...if you do need one,
because they last so well.
 
rebuidling a brake master cylinder..
sure ..'used to be done' more often ..
at least in North America that is almost never done I'd say ..
we just put on a new unit generally ..
a german made one preferred.
 
same is true for the clutch master cylinder ..
the 'usual repair' is a new high quality, usualy german made, one.
 
re
Is there a difference between master cylinder and slave cylinder?
 
Yes..
that's a bit like asking if there is a difference between a wheel and a brake.
like yes there is a difference, and they fundamentally serve different but related functions.
 
the 'master cylinder' whether speaking brakes or clutch, is what you are applying force to with your foot on the pedal.
the cylinder that is acted upon by that force is called ....
it the case of the clutch, it's called the Clutch Slave Cylinder.
or clutch slave for short.
 
in brake..........the rear wheel cylinders are not called slave cylinders ..
their called 'rear wheel cylinders'..  but they are 'slave cylinders' actually , just in brakes they're not called that.
and in the front brakes....the parts the hydraulic pressure is applied to is called the Brake Caliper ..
 
normally you wouldn't put used clutch or brake master cylinders on..
especially the clutch MC ..
it's much to big a pain in the butt to replace ..
you only want to do that once every 6 to 10 years....
they are not fun to replace at all.
 
Brake MC is much easier ..
putting in a used one isn't normally done.
 
you could replace a res and not bleed the brake or clutch hydraulics ..yes.
 
if the brake fluid is at all old..
the old should be removed, and fresh new pumped in.
 
and ....changing the brake fluid in both clutch hydraulic system and brake system ..
will make them last really really well.
not changing it will contribute to them wearing out.
 
when I bleed brakes, as a normal service operation ..
I do all four wheels  and the clutch slave ...like it's normal to chnage out that fluid ..
like every two years at the most.

Many thanks. I'm a bit clearer. My mechanic in Pambula whom I think is OK (he fixed the overheating problem) suggest not to go down the secondhand path to replace the old cylinder unit. He suggest that I buy the unit and he will fit and bleed if necessary. Is there a difference between master cylinder and slave cylinder?

If it turns out to be the reservoir thats leaking,do I need to bleed the system after emptying the reservoir and replacing?
 
Thanks

Michael

Michael,

The reservoir is combined clutch/brake.  The clutch cylinder is fed from the common reservoir and is otherwise unconnected with the braking system.  Your leak could be from the reservoir or it could be from the brake master cylinder, which is also fed from the common reservoir.  If it is the reservoir, it could be a leaking connector pipe or it could be an age crack in the (plastic) reservoir.

If it is the brake master cylinder leaking, it might be just seals.  Seals should be available as VAG spares.  It can also be that the bore of the master cylinder is damaged or corroded.  Most master cylinders can be honed smooth.  This is work done every day by brake specialists.     

In the event that you need to replace the reservoir or the brake master cylinder, they are identical to the two wheel drive T3, so this greatly increases your chances of getting one second hand.  Try Lloyd Davies, Volkspower and Volkscare., but this should be fixable without replacement of the major components.

See notes added to your message below.

Les

Question 1.       Is the brake reservoir both for brake and clutch?

                        Yes


Question 2.       Is that the master cylinder directly under the brake fluid reservoir

                        The brake master cylinder is a bit inboard of the reservoir and lower down.


Question 3.       I believe I may have to replace the master cylinder and or slave cylinder.

 

                        You have to determine if it is the reservoir or the brake master cylinder – see above.

Question 4.       I have looked in the forum links page and most parts suppliers are o/s. After my shock horror of $60 for the cap from Burwin Motors has anybody any suggestions for spare parts. I seem to remember members mentioning a German spare parts dealer, would that be Syncro-Services?

                        It should be fixable locally with a minimum of spare parts.


 

Phil

Will do and thanks

Michael

I think it is around $100 for the clutch master cylinder.

Print the page off for your mechanic.
