if the fluid get on the rubber bladder in the booster, it will cause the bladder to deteriorate destroying the booster. Spend the $70

 

That's a good point, and one I left out. After repairing mine I had no power brakes - the leak had deteriorate the paint on the booster and bubbled it and I could not get a vacuum seal on the booster (tested by spraying brake clean at the flange area and engine speed changed every time). I had to take it apart again, cleaned the mating surfaces of all the bubbled paint and rust, and siliconed that too! No leakage of vacuum out, nor leakage of brake fluid in!

Silicone is impervious to brake fluid and seals quite well to clean rubber.

If anyone looks at this thread months from now and is curious how it is holding up, just ask!

 

The kit is not just two seals. New reservoir, seals, strainer, and clip. 70.00 is much better than 400.00 for a new master cylinder/booster. Brakes are NOT something you should just patch up.

 

It's just temporary until the parts come tomorrow.

 

$70 is ridiculous because landrover selected a rubber that is deteriorate by brake fluid (silicone is not). The reservoir, clip, and filter never wear out - only the seals do - and it is a design flaw. I agree that brakes are nothing to mess with, but I for one don't like spending $70 for a rubber o-ring that should never wear out anyway.

Haters gonna hate

 

since when don't master cylinder wear out? they all do and all the same way thru the rear seal.

 

If you wanna be cheap and not spend 70.00 (which to me is cheap on a LR), you can purchase just the two seals alone for 20.00. The link was provided earlier in this thread. BMW's use the same exact seals on several of their models. It's not a design flaw... More like heat kills rubber...

 

Thanks for pointing out the seal link, somehow I missed it. Ordering now!

As far as THE design flaw - at age 50 I have owned over a dozen vehicle with in excess of 200,000 miles, including Volvos, Audis, BMW's, Hondas, Toyotas, Chevy's, Fords, and Dodges. The Rover is the only one ever to have a leak between the master cylinder reservoir and the master cylinder - its a design flaw.

The weakest link in the Disco generation Rovers is the quality of the rubbers and plastics - from the brittle bumpers to the brittle underhood plastics to the rubber seals that deteriorate when they shouldn't. The engineers at Rover totally blew it when they specified the polymer materials on this vehicle. Just last night I was explaining to a friend who is a new Disco owner all the pieces that might break and frankly it is an embarassingly long list.

Of course, I could be wrong, I'm just a degreed mechanical engineer with 28 years experience designing products in a wide variety of manufacturing industries including automotive and plastics and more than one patent with over a 100MM units sales. It might not be a design flaw, it might something every Land Rover owner is doing incorrectly that causes that seal to start leaking....

 

Sorry but once again every master cylinder fail exactly the same way, i guess you were just lucky with the dozen or so cars cars you had.
i my better than 50 years i have replaced well over a dozen master cylinder in customer cars, well over a dozen

 

Did a little more searching online for the grommets - apparently you can get them for an audi - see this post:

Looks like the best price availabe is around $17 for this one: http://www.new-part.com/product/land...nuine-rtc-5833
