I have an Spitfire master cylinder (MK3 I believe) that appears to have developed a slow leak. Symptoms are the usual required topping up - every 3rd or 4th outing, and a small puddle on the drivers floor mat.
I have what appears to be the dual circuit master with a large clear-ish plastic reservoir. Is there any cheance that it is just the seal at the base of the reservoir? Do these go bad commonly? I'm used to the single circuit masters - but it looks like there is some sort of switch or warning light circuit between the two circuits (is this the PDWA valve I hear about?). But it appears to be disconnected. Is there supposed to be a lead to a warning light somewhere? - if so it was long disconnected on mine ! I'm leaning toward sending the thing out for a rebuild. What is the likelihood of me fixing this thing properly just using a rebuild kit? I suppose I could dismantle and check the bore myself - but it might just be easier to chuck the thing in a UPS box and be done with it. Anyone have an opinion on this. I'm not really convinced I have the experience to judge the condition of the bore myself - particularly since it is working OK at the moment - pedal holds pressure fine. Also - can anyone recommend a vendor for the rebuild? - Apple Hydraulics sounds familiar but that might be those voices in my head again ;-) I hear that these valves can be tricky to center properly. I imagine that the procedure is covered in Haynes - but are there any other tricks to look out for. I have just stripped the whole front firewall area and repainted so really would like to fix this leak before reinstalling the master. Thanks in advance.
