Hi - wonder if anyone can give any adv. please. I have had my espace into 3 different garages regarding brakes, either they did not know what was wrong, or just did not want to get involved....so as much use as a chocolate fireguard!:) ....anyway - brakes starting to fail ...therefore had master cylinder replaced, rear slave cylinders replaced new brake shoes.....system bled 5 times...brakes do not function properly ie...if you need to brake suddenly car does not brake without travelling quite a distance first...have to keep depressing/pumping brakes. Brakes do not feel 'spongey'.....I think there is still a little air in the rear nearside pipe but not really sure....I don't think there are any leaks because break fluid level in resevoir is not going down.....my lovely car is perfect in every other way, so any help would be appreciated...thanks..Linda

It sounds like there may be a problem with the brake servo? I've never had this problem before but I'm sure there will be someone who has on here.

Thanks for quick reply, will look into brake servo, any idea if it's a big (expensive) job?

What Espace do you drive, is it the 1990 2.0? If it is then assuming it is the servo, the price for a new one from Euro Car Parts UK - European Car Parts is £124.14. I have no idea the cost of fitting unfortunately, but before you go to a garage asking for prices, make sure it definately it is the servo because it might be something really simple that the garages missed. I may be completley wrong so try and get a second opinion.

Thanks Marty, yes it's the 1990 2.0...I will wait to see if any further replies before looking into servo further....although, having said that, it's worth it!

Hi tired - What sorta conditon are the front brakes in - could be seized or sticky calipers. I would check them out before going for a new servo - not that fixing them may be a cheaper option but it would cost very little to check out.:)

Thanks for reply, - calipers have been cleaned and had all external dirt removed. One garage did diagnostics test...after checking, decided it must be the master cylinder...which was then replaced, and all the system bled....looking like could be servo??!!

It definately sounds like the servo to me. The fact that you've bled the brakes 5 times would indicate that air is getting into the system somewhere, maybe a leak? Get someone to pump the brakes and have a listen for hissing under the bonnet around the servo and vacuum pipes.

Oops Marty - all servos in good condition make a hissing sound so its easy to get mislead by listening for hisses, etc. After runng the engine for a minute or so the servo reservoir should be fully charged - To check switch engine off depress the brake pedal and listen carefully you should then hear air entering the reservoir. This should happen on at least 3-4 pumps of the pedal. If not I would suspect the reservoir is not being charged or the reservoir diaphram is leaking. There could be a leak in some of the vacuum hoses going to the servo or the servo itself is duff.:)
