Can anyone give me any advice about a master cylinder please

[ballbag]

Right, I fitted my new CSP discs today, which incidently could be the easiest thing I've ever had to do on my bus :mrgreen:

I've come to fit the new master cylinder and it's a bit different to my old one. The old one has two outlets for the front brakes, 1 left and 1 right and 1 outlet heading of for the rears. 2 holes at the top for the resevior and 2 more on the side for the brake light switch.

The new one only has 1 for the front brakes and 1 for the rear brakes and the others I mentioned.

What I need to know is, do I just simply use a T-piece?

All the master cylinders on the machine 7 site where its from are the same.
I'll get some pics in a bit.

Hi Ballbag
From what you have explained,it sounds like the M/C is the same setup as
as my 72 with discs. Just put a T piece on the front and you should be fine..Dave

I did mine by only using one brake switch.

So you will have one going to the back and splitting off and two to the front and one break switch. (It has been working for 2 years, 2 MOT's and 7000 miles ish)

If anyone knows if only having the one switch is a problem let me know.

Hi dudes, thanks for the replies. I emailed Michael Leche last night and he came swiftly back with this.

Hi Jay

Hope you are well.
Must admit, that I have never fitted one on a bay, have only fitted split bus ones.

There is no problem at all, in installing a T-piece, but this would only be required if you want to retain two brake light switches ......

This is the MC that we should have supplied –

If I can recall correctly, the two connections furthest away from the plunger, are used for the front brakes, one for each front brake.
Then, the two nearest the plunger are used for the rear brakes and for the switch. The upper of the two ports is used for the rear brakes, with a T-piece at the rear of the vehicle.
The switch should always be fitted to a horizontal port, not one angled upwards, or you will have problems bleeding the brakes.

You will only end up with one brake light switch, instead of two, which won’t cause any problem (many VW’s only had one anyway). The only reason some have two, is so that if you have lost half of your brakes due to loss of fluid, your tail lights could fail. Split bus and Beetle installs from CSP only use one switch.

However, If you do definitely want to use two switches, I would suggest adding a Banjo bolt onto one of the front ports. I can check this with CSP for you on Monday if required, they should be able to supply the banjo )

Either way, it’s not going to hold you up, continue and install as per above, then decide whether you want to add the second switch back in with a Banjo (although you will have to bleed again obviously).

Hope this all helps.

One switch it is :mrgreen: 8)

I'm glad it's solved. I did have to extend one line by about 3 inches but was only a 10 minute job. Good luck.
