Man On The Clapham Omnibus Posted August 21, 2007 Share Posted August 21, 2007 My brakes are spongy and the pedal goes well down to nearly the end of its travel. I have bled the system extensively and still the pedal is 'soft'. In the master cylinder reservoir there is a sort of black particulate matter which I assume is rubber from the seals which are probably over ten years old. The car (SEiW) was built in 1994 and has top mounted pedals with a standard Westfield supplied master cylinder. I think the cylinder seals should be replaced but Westfield quote only for a new complete cylinder here. Is it possible to buy a repair kit from a parts supplier? What car does the cylinder come off so I can order it? Quote Link to comment Share on other sites More sharing options...
Man On The Clapham Omnibus Posted August 21, 2007 Author Share Posted August 21, 2007 The answer to the above is that a repair kit is available for the standard Westfield tandem Girling type master cylinder. The old Girling number for the kit is SP7657 and the kit is made by Past Parts click here under their part number 17-1032. So if your master cylinder has Girling written on it and looks like the one on the Westfield site, and its casting number (underneath) is 74660152, this kit should be for you. I got mine from LCP Automotive in High Wycombe - branches all over the home counties. Not having yet fitted mine at the time of writing, your mileage might vary, as they say. The storeman did say it was an equivalent and the 'proper' one might be SP7693 Further edit after speaking to the man at Past Parts. The only difference, he tells me, between this kit 17-1032 and the 'proper' kit is the seal for the reservoir cap. Hardly important. I really must recommend Past Parts for their customer service.

AdamR Posted November 26, 2013 Share Posted November 26, 2013 I realise this is a huge bump, but just wanted to say thanks for the above info - got a 17-1032 kit through today. Price was relatively high (£30 once VAT and postage had been taken care of) but hoping it does the trick! Thanks again. Quote Link to comment Share on other sites More sharing options...
Man On The Clapham Omnibus Posted November 26, 2013 Author Share Posted November 26, 2013 Adam, I hope it does too because as time passes, these things will become harder to source... Quote Link to comment Share on other sites More sharing options...
AdamR Posted November 26, 2013 Share Posted November 26, 2013 True - almost makes an upgrade to twin masters and a bias bar look like a more efficient solution all things considered...! Quote Link to comment Share on other sites More sharing options...

thall1 Posted May 18, 2018 Share Posted May 18, 2018 Hi, new to the site, I've got an '89 SE that I built. I've put it back on the road after 15 years stored. New pads and seals fitted to the brakes but the brakes are shocking compared to modern cars!.. its fitted with a non servo Cortina mk3 so I appreciate its never going to be brilliant but id like to get it better. I suspect the master cylinder bore is worn and despite new seals the brakes always feel spongy and pump up on braking. It'll be a shame to replace it as I made a stainless reservoir to replace the plastic 'spigot' type that was originally fitted which required mods to the cylinder body to achieve a leak free, removable reservoir. Do any of you know of a modern 19.0mm bore master cylinder and reservoir that will fit without modification to the mounting holes? 1 Quote Link to comment Share on other sites More sharing options...
Mighty Mart Posted May 18, 2018 Share Posted May 18, 2018 Thall1, that looks very clean and tidy mate...a credit to you IMHO. hope it's back on the road soon! Mart. Quote Link to comment Share on other sites More sharing options...
thall1 Posted May 19, 2018 Share Posted May 19, 2018 hi Mighty Mart. thanks for the nice comments...its not bad for almost 30yrs old!..its on the road, has been since 2015, not that I use it much...just a couple of hundred miles or so each year now...its only got just over 16000 on it now...just a shame it doesn't stop!...it may be that there isn't much wrong with it but its been so long off the road I may have forgotten how bad it is!..

Mighty Mart Posted May 20, 2018 Share Posted May 20, 2018 To be honest, being so light, the brakes 'should' be very good. Even reasonably big power shouldn't need big brakes IMHO. my m16 calipers and drums on the back work as well as any car I've had actually...think I've got mintex 1144 pads on the front though. Mart.

thall1 Posted May 20, 2018 Share Posted May 20, 2018 different pads on the front was another thought... I may go down that route first...thanks for the info on yours... Quote Link to comment Share on other sites More sharing options...
Martin Letts - Joint Hampshire & IOW AO Posted November 21, 2018 Share Posted November 21, 2018 Sorry for leaping on your bandwagon, but could you cast any light on my master cylinder ie where can I get a new one, it is off a 1989 narrow, any help gratefully received Quote Link to comment Share on other sites More sharing options...
Man On The Clapham Omnibus Posted November 22, 2018 Author Share Posted November 22, 2018 Try Past Parts Quote Link to comment Share on other sites More sharing options...
Dave Eastwood (Gadgetman) - Club Chairman Posted November 22, 2018 Share Posted November 22, 2018 From previous posts, I have a feeling it was rebuild kits only on that one. I’ve a vague memory that one of the specialist might be able to recondition them, including re-sleeving the bore. But that’s about it.
