I have refurbed and put 11' TLE drums on front of my S2, will this need a S3 servo I have one that have cleaned and painted but not sure if it's worth changing the set up.
 
you dont need the servo brakes will work just fine without albeit requiring more pressure from your foot but they do make them feel better and its not a lot of work to fit 1 although if i remember correctly the series 3 servo type brakes also had a different master cylinder set up i have a remote servo on my s1 and it does make the thing stop quicker

It was one I picked up off eBay, bought it through recommendation.
The servo uses pressure from the engine to help stop the vehicle with much less effort.
I am no expert and sure others can tell you more or try a google search...
 
You should have a LWB master cylinder with this set up otherwise you could end up with a long pedal travel.

If you have a diesel and you fit a servo you will need some way of creating the vacuum.

as above the servo uses vacuum from the engine not pressure so if you have a diesel an exhauster or electric pump is reqd

Ive just bought peugeot vacuum pump- not got around to fitting it yet. Once done I will fit the servo.
 
Much easier to fit an electric pump. Took me less than 2 hours and £70 for a new pump. Works off the brake light switch via relay.
 
No link was a few years ago now. Hella U28 (badged as a Volvo part) off ebay from a bloke in Holland. Works really well apart from hearing it buzz when sitting with your foot on brake. Easy install, blanked off the diesel butterfly flap nonsense, less smoke. Big advantage is full servo with ignition on even if engine not running. Useful if stalled on a hill or being towed.

Don't suppose it matters that mine is a petrol?
 
Yes but I had the pump and the pulleys are there ( I read on another forum that using the brake switch to trigger the VAC pump can lead to a delay in servo action)

The servo should keep the vacuum, unless you have a leak. With your engine switched off, it should take a couple of pumps of the brake pedal to use up the vacuum. Try it on any car, it will be the same.
 
" dont suppose it matters that mine is petrol" Petrol engine only requires inlet manifold tapping to get vacuum so easy to add servo. Diesel is a whole different ball game to get any vacuum from.
