Hi Everyone. I think I know the answer to this already but before a spend £100 plus on the answer I thought I would run it past a few of you. Car is a Defender 110 TD5 non ABS. I replaced a front brake caliper, 2 front metal brake pipes around the engine bay and the brake master cylinder and now cannot bleed the brakes. Using the 2 man method with a glass jar and hose I can see the fluid isnt really moving at all. I trimmed the old pipes and refitted them from the master cylinder back around and into the reservoir... guess what the fluid doesnt move and the reservoir just "gurgles". Do I need a new Servo? And why would it fail when it was working 2 weeks ago?I did all the work because it failed MOT for rusty brake pipes. The master cylinder was questionable as a mechanic rebuilt it last year and said I should fit a new one when I got a chance.

you need to bleed the master, undo the steel pipes and get someone to press the pedal whilst you use your finger as a oneway valve over the port,that or masters buggered
Thanks James. I thought by using 6" of the old pipes back around and into the top of the reservoir I was bleeding the cylinder? didnt want fliud spraying everywhere.... Or is there a knack to the finger method ie pressure on the upstroke?

Persist with bleeding the brakes, a servo, knackered or otherwise will have no effect on bleeding the brakes.

Make sure calipers have bleed screws at the top too 
OK Thanks - ****ed it down all day in Ireland yesterday
Done ThanksMake sure calipers have bleed screws at the top too
Of course purely mechanical.....
Sorted, thanks all. Sheer persistence in the end as it took about 2 hrs in the rain. One interesting observation. The wife suggested running the engine to increase pressure (I think she really just needed the heater on whilst pumping) and things seemed to go a lot quicker from there. I tried to explain that the servo increased pressure not flow ...... perhaps the heated cabin meant she pumped faster!
