Brake master cylinder

gavin.starr · February 15, 2011, 04:05:17 PM

One they are paid for and in my hands I am doing a rear disk conversion onto my polo.

just a question regarding the master cylinder, im currently on my standard one from the 1.3 bready beast, so will i need to upgrade it to accommodate the new callipers on the back or can I still use it, if i do need to upgrade what are the recommended upgrades available

Cheers

Use a master cylinder from whatever car the brakes have come from, then it should be fairly well matched. If not already fitted, you will probably need to fit a rear brake pressure limiting valve too.

The brakes are from a G40, but im also doing a rear disk conversion at the same time too.

Im wondering if the 22.2 mm one of a Passat would be better suited and if so which year of manufacture of passat do I need?

I always find that's a good upgrade for Polo's. I ask for a 1995 Corrado VR6 Non ABS 22.2mm master cylinder. Makes the pedal feel a lot better. Not bought one in a while but they're about £40 from GSF from memory.

If it's as i desvribed then yes

No point buying a 2nd hand one at that price when you can buy a new one for the same money? you could get that and it could fail within 10 miles, with no warranty on it......more importantly could result in death/injury/ broken car

just buy a new one, they're like £20

Have you got a part/serial number for one so i now im buying the right one.

Is it this one:

http://secure.gsfcarparts.com/shop/basket.asp?make=VW%20WATERCOOLED&model=CORRADO&Category=BRAKE+SYSTEM+(HYDRAULICS)&keywords=

Is there some where else to get one as they come to £46.98 at the check out.

Cheers

that link doesnt work, you almost can't buy the wrong one as long as it's for a late 1980s/early 1990s vw and it's the size you want then it'll work. they came on loads on cars.

maybe my price estimate was a bit out of date though!

Its this part number (652VG0250) on the GSF website. says it for a Corrado on the drop down list and 22.2mm but when you go on the add to order page it calls it up for an Ibiza does that sound correct.

Sounds like GSF's website! So long as the part number matches it should be fine

I know it's a little more but there's nothing more disheartening than pushing the middle pedal and not getting the result you want. The seals fail, or flip round or something and provide little/ no stopping power when they go= pooey pants

they're nearly all the same. if you buy one for a mk2 golf gti 16v then it's definitely right, that's what I have

Do you have a part number for yours, if not could you check and see if this one is correct on the GSF website.
