Great video as usual Mike. I have replaced the servo on my 300tdi twice now, it has 260000 miles on it so not too disappointed. One thing which I think you could cover which doesn't seem to be in any of the workshop manuals is servo actuator pin adjustment. The most recent unit that I fitted this was well out causing a very low pedal and sudden brake feel. Explanation of the setting up may well help many of your followers. 👍

@BritannicaRestorations 11 месяцев назад

There should be no reason to adjust the pin - yes it gives a better pedal - until the brakes heat up, and the expanded fluid, can no longer return to the reservoir as the seals shut the return off - this can result in the brakes overheating, so for liability I do not offer this advice I hope you understand

@johnlippiatt8200 11 месяцев назад

@@BritannicaRestorations Clearance on the unit I most recently fitted was 30 thou from the manufacturer, I had never had to adjust one previously on a Land Rover or any other vehicle. Not shown in any manual that I could access in the end I had to make tool to measure the clearance. Once set all worked correctly, fluid returned to reservoir , no overheating now been functioning OK for 12000 miles. Understand your point regarding liability, do you want me to delete my post?

@BritannicaRestorations 11 месяцев назад

No - don't delete - but you can see it is a very fine line between good brakes and dangerous = I have seen someone's vehicle lock up the brakes completely due to over adjustment after driving round town This is why there is no mention of this in the manual

@petermenzies1714 11 месяцев назад

Absolutely brilliant explanation and crystal clear illustration of the cause of this quite common problem. Tdi’s will now be more expensive when panic sellers begin to realise t’s the brake servo not the engine which kaput and pressuring the crankcase.

Thank you Sir ! It's interesting for me because I've got à defender 90 300tdi 2006 march

Enjoy it!

@TheNorthernExplorer 11 месяцев назад

Great info! After your advice on the previous video I’ve ordered a second hand unit to see if it fixes my problem. I also have an issue with oil out the breathers so this could be the root of all evil! Thanks for the info!

I learned something there Mike ,great video ,thank you.

@BritannicaRestorations 11 месяцев назад

Glad to hear it

@Reaper4367 11 месяцев назад

Great information as usual Mike. My breaks are good, for about 3 seconds on the pedal then the pedal starts to drop towards the floor. Cheers for sharing.

@BritannicaRestorations 11 месяцев назад

Good stuff!

@nigeljefferies8713 11 месяцев назад

Great video, having just replaced mine which was part hard pedal and normal whiich was very disconcerting. Always check the valve being a one way flow to the engine and not both ways. My unit was 27 years old. Thanks again Mike you deserve to have a lot of followers. Regards Nigel

@cdnrover 11 месяцев назад

Geez, I didn't know it was not working properly mate. No symptoms, good break and no excessive back pressure. The master cylinder never needed topping up. Might be a consequence of all those years driving old Land-Rovers, you get used to bad car!

@BritannicaRestorations 11 месяцев назад

@MARTINA-gc3tq 11 месяцев назад

Many years ago, a pal was working on his TR6 which had a brake issue. His servo was cracked and he repaired it with glass fibre mat and what I assume was epoxy. He often worked on his glass fibre speed boat so I wonder if he got the idea from that.

@BritannicaRestorations 11 месяцев назад

I have seen plastic servos in the past -- after market, but I never see them now

@PeasantPrep 10 месяцев назад

Having issues with the servo on my d1 getting engine oil in. This is the second servo this has happend too so going to change the vac pump aswell. Im guessing there is a one way valve that may of failed.

@BritannicaRestorations 10 месяцев назад

Maybe - the engine takes air from the servo, but does not pump air in from the engine

@jameskerr5756 11 месяцев назад

Interesting Mike. Mine looks as though it has been changed not too long before my ownership so seems to be still good. Presume it would be the same symptoms on the V8.

@BritannicaRestorations 11 месяцев назад

You should be OK as it should have the older style servo - much thicker

@scottthomasmartin 9 месяцев назад

With these servo issues, do you think it's a bad idea to connect the breather to the intake? Should the hose off the breather terminate somewhere else so that we don't get oil in the intake pathway?

@alfredsteidle5035 11 месяцев назад

Thank you for this excellent Video😊. Maybe you can show us the inside or the Membran ? Is the rubber good ? 👍👍👍👍👍👍👍

@BritannicaRestorations 11 месяцев назад

I have a video somewhere when I stripped a servo - but there is not much in them and every one I have looked has been cracked - never experienced a diaphragm broken

@alfredsteidle5035 11 месяцев назад

@berndeikers8924 11 месяцев назад

Would be evt. Helpful to know how many years thie booster was in service, how many and what services have been made? The problem of the booster is huminity getting in and doesnt come out. That means rust, that means the material gets weaker

@alanhowatson3462 11 месяцев назад

I changed a cylinder head out once for excess back pressure, only to find out the servo was kaput!

@BritannicaRestorations 11 месяцев назад

Easy done!

@alanhowatson3462 11 месяцев назад

@BritannicaRestorations it was something you mentioned in one of your videos about how the 300tdi servo was thin and prone to cracking that led me to the servo. So thank you Mike. Top bloke👍

@BritannicaRestorations 11 месяцев назад

Yes an easy trap to fall into! Even happened to me!

@smifflarr 10 месяцев назад

Could this be the case with any car or just specific to land rovers?

@BritannicaRestorations 10 месяцев назад

Any vehicle with a servo/booster

@erictyrrell3560 11 месяцев назад

200Tdi booster may have been the last one made of sufficiently thick metal

Indeed - the TD5, disco and puma seemed to be made of sterner stuff
