Raider Posted January 16, 2005 Share Posted January 16, 2005 I don't know enough about Dolomites I am afraid but the Princess calipers fit TR7s OK apparently.Why not have a word with Brian Kitley or if you are a Club Triumph member you could e-mail our Dolomite consultant, Jim Webb Link to comment Share on other sites More sharing options...
Silvery Posted January 16, 2005 Share Posted January 16, 2005 As far as I know, Princess 4 pots are quite a straightforward fit, but on the hard side to find any nowadays.There is a mod involving Sierra discs and callipers that seems to be not at all bad, requires some machining though, which is done by someone in Devon. Not sure if anyone here has done this, it's been quite common in the TDC though.It's around 100 quid IIRC for the work and bracket to fit the bits, plus the cost of Sierra parts. Trouble is, I think the person who does the work does them in batches, not one offs. Worth looking into though :) Link to comment Share on other sites More sharing options...
rich Posted January 16, 2005 Author Share Posted January 16, 2005 I'd love to do the sierra conversion but dont know who to contact and from what I can gather you need 3 or 4 lots to keep the price down, can any one help? Link to comment Share on other sites More sharing options...
Tim Bancroft Posted January 16, 2005 Share Posted January 16, 2005 Do as Raider says and speak to Brian Kitley.However for now try the car with the bits that you have plus braided hoses, new fluid and see how you get on- what about the rears- no point going further at present if they are not too bad.My GT6 has newish calipers,braided hoses, green stuff pads, new rear linings, new wheel cylinders and master cylinder- no problem, in fact was outbraking TR's at last years TR Reg. Track Day at Mallory. I suppose I am used to them, but I find the brakes not much worse than those on moderns. Link to comment Share on other sites More sharing options...
rich Posted January 16, 2005 Author Share Posted January 16, 2005 thanks for the info lads,maybe I've found another avenue,A pair of st front calipers with vented disc's all attacted to their vertical link ready to bolt straight on , seem to good to be true!

dolomiteman Posted January 17, 2005 Share Posted January 17, 2005 Princess 4 potters will not fit behind a standard Sprint Alloy. Link to comment Share on other sites More sharing options...
rotten herald Posted January 20, 2005 Share Posted January 20, 2005 nore will the serria ones withut shaving little off rim, works fine, n there is plenty of strength in the wheels, its what u do if u race them. my wheels are all Xterry V, half of them have been shaved. i also got P 4 pots on my toledo, but got marina tc steels hiding them, they make one hell of a differenceDave Link to comment Share on other sites More sharing options...
SprintV8 Posted January 21, 2005 Share Posted January 21, 2005 I WOULD NOT RECOMMEND MODIFY THE ALLOY WHEELS BY REMOVING METAL TO CLEAR BRAKE CALIPER'S ETC. Link to comment Share on other sites More sharing options...
2Toledos Posted January 21, 2005 Share Posted January 21, 2005 I thought the 'generally approved' method of getting the Sierra calipers to fit, was to grind back the top of the caliper casting ?! Can't say I'm too keen on the idea of 'shaving' my alloys :-/ Link to comment Share on other sites More sharing options...
rotten herald Posted January 21, 2005 Share Posted January 21, 2005 its trur bit off the calipers wouldn't go amiss, bt as said before i didn't do just benifit for improved breaking experiance Link to comment Share on other sites More sharing options...
Toledo Man Posted January 21, 2005 Share Posted January 21, 2005 I heard somewhere that fitting vented discs would improve things. I know it's not that simple but that's one idea I've come across.Why did Triumph use the same front brakes on the Sprint as the Toledo??? Link to comment Share on other sites More sharing options...
2Toledos Posted January 21, 2005 Share Posted January 21, 2005 This is BL we're talking about ! Of course you're right, though - the 2000 brakes would have made much more sense.Look on the bright side - at least it has discs on the front. If the 16v had been developed a few years earlier; it would have been on Toledo drums all round ! Link to comment Share on other sites More sharing options...
rich Posted January 21, 2005 Author Share Posted January 21, 2005 how easy is the sierra converion and is it mainly the vented discs that make the differents ??) Link to comment Share on other sites More sharing options...
Mad Mart Posted January 22, 2005 Share Posted January 22, 2005 The conversion is not that difficult but you will need a special bracket made up. I have all the details necessary but Jon, who designed it, has changed jobs recently so can't make them up anymore. Any good machine shop will be able to knock these up though.The Sierra discs are slightly bigger (can't remember the diameter off-hand), the pistons and pads are also bigger. They do give the Sprint brilliant stopping power being that the original brakes were always marginal anyway.Have a look on my website. I did the Sierra brake conversion on my track Sprint last year.

rich Posted January 22, 2005 Author Share Posted January 22, 2005 looked at you're site a few times mart, the more i look the more i get my head round it , just two things puzzle me , first thing is the hub machining (how much,where)and secondly the bracket , who made you'res up for you ,seems that would have to be just right , square to the disc and so. a bit much for a bricky!

Mad Mart Posted January 28, 2005 Share Posted January 28, 2005 You'll have to make some local enquiries for machining. The guy that machined mine charged £80 but, as I said, he's no longer able to do it. I can provide a plan of the bracket with all necessary measurements & material requirements. Just take the details to a machine shop & ask them how much to knock a pair up.Martin Link to comment Share on other sites More sharing options...
