Lord Sorbington Posted March 24, 2007 Share Posted March 24, 2007 Driving my 2000 today, i noticed the brake pedal felt a bit soft, sure enough the fluid level was low.As there is no warning light, i check the level at least once a week, so every 50 miles or so on average.The only leak I can find is on a wheel cylinder. The drum is dry inside - would this really have caused such a quick leak? Could the master cylinder be leaking into the servo or something?Hopefully the low level was just caused by the wheel cylinder leak but if the master cylinder is at fault, is there any scope for upgrading the system, perhaps with an alternative master cylinder? You can never have enough brakes..... Link to comment Share on other sites More sharing options...
Vitesse2l Posted March 24, 2007 Share Posted March 24, 2007 Hi,When I have had a leaky cylinder, it's usually running down the tyres. Very obvious. Tends to be a mess inside the drum too...Never played with the 2000 m/c. It might be possible to check for fluid in the servo through the vacuum pipe connector.If there is any chance of your rear shoes being contaminated, try blasting them with a hot air gun. Any fluid will quickly bubble up to the surface.cheers, Steve Link to comment Share on other sites More sharing options...
mikeyb Posted March 24, 2007 Share Posted March 24, 2007 Good luck if it's a Lockheed one - right pain in the ass to bleed - as we found out last year with Gerties brakes and more recently the PI's clutch.Gertie also had a good pint inside the servo - if you rev up hard and get lots of white smoke as the revs drop down again, it could be that you have fluid in your servo. A BMW servo I'm told will fit (5 series I think) but I have never seen such a conversion. One of the Stag specialists (Monarch) offer a BMW conversion though.

Lord Sorbington Posted March 24, 2007 Author Share Posted March 24, 2007 It is a Lockheed system so could be in for some fun! Can't imagine I've lost a whole reservoir of fluid through a leaky wheel cylinder - I had to pull back the cylinder dust cover to see the leak.I'm surprised this hasn't happened sooner, the car was abandoned in a garage for 10 years, then sailed through its MOT last September, no problems. The brakes have performed superbly until now - linings good, not seized, good hoses, plenty of power, drums/ discs as new. As a result I've been watching them like a hawk as it seemed too good to be true! Even after the pedal went soft I could lock the wheels easily. I've certainly had my moneys worth!

Deleted User Posted March 24, 2007 Share Posted March 24, 2007 There are 100's off SH dual circuit MC's over here.... fancy one?Basically Stag servo and 13/16 cylinder versus 7/8 on a Stag Link to comment Share on other sites More sharing options...
Lord Sorbington Posted March 25, 2007 Author Share Posted March 25, 2007 Looked into the potential upgrades from Monarch but would cost more than the car is worth. Shame, I quite fancy having discs all round!Looking at the section views in the manual, it's got to be the master cylinder causing the problem, leaking into the servo I'd guess. Investigation pending..... Link to comment Share on other sites More sharing options...
Lord Sorbington Posted March 28, 2007 Author Share Posted March 28, 2007 All sorted now - wheel cylinder replaced, great to have the old beast back!! Will keep checking the fluid level though and will keep a m/c cylinder seal kit around.Was impressed with the garage who did the work, within walking distance of home , which is handy. They insisted on quoting for the work first and the bill was exactly as per quote. I got them to do the drag strut bushes while they were at it, came to £159 for the lot, including VAT , a complete brake fluid change and supply of the bits.Brakes feel nice now - may try some Greenstuff pads on the fronts soon.Spent a while chatting to the owner about his old Beetle, to which he's fitted an '80s 911 engine!

Tim Bancroft Posted March 28, 2007 Share Posted March 28, 2007 Let us know the name of the garage, could be of use to anyone in the area. Link to comment Share on other sites More sharing options...
Lord Sorbington Posted March 28, 2007 Author Share Posted March 28, 2007 Brooklands Garage in Dothill, Wellington, Telford. They went out of their way to help as finding a 2000 brake cylinder was a bit out of the ordinary for them. Link to comment Share on other sites More sharing options...
