I am going to no servo on my S4 before I (perhaps) go to plus two brakes. I have just picked up a 5/8 inch Master Cylinder (was 0.7). Does anybody know which are suitable high friction soft front pads (Non Servo type) that are avaiable in the UK. Only for road use.
I am told that Green Stuff has changed and is now too hard for no servo.
Interested in new old stock etc. Thoughts appreciated!
Mike 
Interesting as I am currently using Green Stuff on my no server +2 brakes S4. Still plenty of pad left though
If they have changed the formula I would also be interested to know what other pads are available.
hi this is a nice easy one , i have raced my s4 at knockhill this year , and run the standard brakes, i removed the servo halfway through the season and found the brakes much improved, one thing i did do was to use the pads out of a +2 , yes the pads are bigger, so what i done was to put the s4 pad back to back and mark where i cut with hacksaw , and then drill new hole for the pad retaining pin to slide through, , the benifit you get is the area size of the pad it now covers the full size of the disc, with this easy convertion on a standard master cylinder, never ran out of brakes cheers del
Steve,
I have been in Classicar Automotive and had a good natter, they are having a look for softer pad alternatives. I will post what they say. Good guys!
Del , Plus two pads sound interesting. I think I have some old ones in the garage. I will have look at this. Are your pads any particulr type or just bog standard?
Does anybody know if the S4 Elan calipers will take the same pads as the S1 Elan. I see some Truimph spitfire/Elan S1 pads as ācheap as chipsā on ebay. I emailed but got no answer yet. Cheap not being the point but perhaps soft?:?
Mike
Sue Miller had some soft pads when I took the servo off my sprint . I did rebuild and refit the servo as I think itās better for general todays type stop and start road use to have the servo .
Neil
The S1 Elan had Type 12SP calipers, whereas the S4 had Type 14LF. The 12SP pads are different, and are about 1/8" shorter. I have heard people say that you can grind down the type 14 pads to go into a type 12 caliper quite easily, but they wonāt work the other way around. Thereās also less surface area on the pad, so the performance wouldnāt be as good, even if you could.
Paddy
CAUTION Before fitting ācut-downā pads in place of smaller ones, PLEASE make sure the pad material does NOT overlap the edge of the disc. My car came with a set of cut-down pads (from the US in the days when original parts must have been hard/expensive to find!). The friction material overlapped the outside of the disc and had worn so that the overlapping parts met i.e. not much braking power since they were pushing against each other on one sideā¦ 
This may explain the (badly repaired) front end accident damageā¦

I took my servo off and fitted a 5/8" m/cylinder and Greenstuff pads supplied by Paul Matty about a month ago. The brakes now work much better than they did with the servo - I was very pleased with the results.
You might try Paul Matty to see if they still have any in stock.
Thanks for the information and advice guys. I will do some calls.
Re; the EBC Green stuff, do you know what the part numbers are. Do you still have the box?
Mike
I ordered Greenstuff pads from powerstop.co.uk to fit type 14 LF caliper. My sales receipt shows:
Part number: DP2114
I donāt know if this is an EBC part no or a powerstop number.
Paddy
Sorry for the slow response - iāve been away from home for a couple of days doing the Christmas rounds!
Yes, Iāve still got the box. Itās marked EBC DP2114 Ford Cortina/Escort Mk. 1/ Lotus Elan/Europa/Seven/Volvo 140/160/240/260 series.
Interestingly, itās also marked up with Paul Mattyās parts code JPSF026C, which is listed in their catalogue as āFront with Servo Greenstuffā, although I specifically asked them for non-servo Greenstuff pads.
Whateverā¦ they work just fine and Iām very pleased with them!
Hi
Interesting comments since I still seem to be having problems with plus 2 fronts on a sprint. thinking about the two systems (std sprint and plus 2) the pedal travel surely must increase since the 0.7 m/cylinder Iām using now has to displace larger pistons. Fitting the smaller (5/8) one must make that āsofterā pedal more pronounced.
One thing I have noticed is that EBC plus 2 front pads are definitely too hard for an unservoed system- Iām currently trying non servo spec pads for a Triumph GT6. As Iāve said before pads made years ago must have been a lot softer- the S4 I had in the mid 70ās was unservoed and I never noticed the brakes- and switching to the sprint in 1978 I donāt recall noticing them either so as my driving style didnāt alter there couldnāt have been much to choose between them for stopping efficiency.
Incidentally, my complaint about the non servo system are not my imagination- the recent MOT pointed out that the brakes were āmarginalā and only just met the minimum requirements.
As Iām certain my system has no air present and the hoses are not ballooning Iām pretty sure the (relatively) poor braking is due to the pad material. Symptoms- best way I can describe them is that initial stopping from say 40-50 mph is ok but pressing harder is not translated into equivalent stopping ie the system is not progressive. Free travel of the pedal is fine and with all 4 wheels off the pstons at each corner are beginning to grab after only a small movement of the pedal.
Ideas still welcome on this one.
Regards
John
Pedal travel ceratinly increases in comparison to an unservoed car with a 0.7" master cylinder, but when you take into account the effect of the servo (which also creates a āsofterā pedal, remember), an unservoād 5/8" master cylinder doesnāt feel all that much different to a servoād 0.7" one.
I did my conversion in āstagesā; first I changed the hydraulics and bled the system, but left the original (standard) pads in place. esult was very disappointing (similar pedal āfeelā in terms of softness/pedal travel as with the servo, but very high pedal pressures required to stop the car).
I was actually quite despondent at this stage, thinking Iād have to re-fit the servo. Then I changed to the āGreenstuffā pads, which transformed the brakes. I can now lock the wheels up with less pedal effort and more predictability than I could with the previous (Lockheed) servo in place, and the pedal travel is approximately the same as with the servo.
Been busy, sorry for slow response. Thanks for the information requested.
I have the servo out now, and the 5/8 inch M/C fitted. Did an intial bleed up. Old pads still in yet. Need to sort some new ones out. Working on it. Good to hear some success.
Mike
Some while back I binned the servo on my Sprint, fitted +2 front stuff, with Classicar Automotive cheapo pads, rather than greenies. I read loads of āopinionsā beforehand and, having thought it through, decided they were no more than that, I kept the original master cylinder (actually a new one of the same size). Works brilliant, as the football manager said.
If I were you, I would replace the original master cylinder and see how that is.
Just an opinion. 
Only my opinion,
But all this talk about hard / soft pads, servo / non servo isn?t relevant as the only thing that matters is the lining ? not the compressibility.
If you cut down type 16 pads to fit a type 14 caliper and the lining material is the same type then the performance will be the same ? friction is not dependant on lining area but a larger pad area would reduce the lining load.
John,
Your problems don?t sound pad related. If the performance is as you describe ? increasing pedal force does not translate into increasing deceleration then it?s either
The calipers don?t see the increase in pressure ? hose problem or blockage else where.
Seized caliper pistons
Faulty master cylinder.
I would look at the hoses first - did you clamp the hoses when you changed the calipers?
Regards
Steve
But the different pads being discussed perform differently because the pad materials have different ? values, and whilst ultimate braking effort is depent on the pads, the m/cyl size and servo (or lack of) will dictate the pedal travel and pedal effort needed to achieve it.
Fitted Green stuff pads this morning (5/8 M/C fitted and Servo was removed). Below is my initial view/opinion after about 60 miles (today). Bearing in mind the pads are not bedded in yet.
Pedal travel does not bother me. I actually like it as it seems to have a progressive feel to it as it goes further down and the nose drops. The new pads were better than the stock ones within a few miles. They are getting better now after about 60 miles. I am not crapping myself and feel happy with the outcome. I have (in the past) driven with standard pads without a servo and 0.7 M/C and I felt nervous as the pedal seemed to go rock hard and the car was only pulling up slightly.
Whan I have some more miles on, I will report back. I think these are going to be fine.
Mike
