csopelario Posted December 12, 2004 Share Posted December 12, 2004 I am very new to TR7s, but chassis-wise, they are similar to the Toyotas I usually am around I have a 76 Toyota Celica liftback).Me and my brother have finally gotten our father's coupe '76 tr7 (4cyl) up and running. We are looking into brakes. We have already ordered Brembo OEM rotors and EBC green stuff for the front setup and brand new rubber hoses (didnt have the $ for braided).I have read a few of the posts here and noticed the Capri come up as an option... is this true? direct bolt on rotors or modification required? Can TR8 front disk rotors bolt up to the TR7 (4cyl) chassis - one in the same?Becasue I have been with Toyotas for a couple of yrs now, I know about a few swappable items from other cars... Corolla AE86-GTS rear shocks/LSD are direct bolt ons with my Celica, front struts from an early 70s carina are direct bolt-ins (with spacers), etc.,... Is there cool swaps (and money saving tactics) I can use on the TR7's suspension, brakes, chassis stiffening?Oh, I am in Northern CA, USA.Thank you for the help--Cat Link to comment Share on other sites More sharing options...
Raider Posted December 12, 2004 Share Posted December 12, 2004 Hi - there are a few options ranging from low to extremely high cost. They also range from simple to difficult ::)Our very own TR7 guru (Ellis) has a web site with a projects section - follow this link http://www.triumphtr7.co.uk/projects.htmlYou can also buy complete kits from companies such as S&S preps in the UK who I use and are very good http://www.ss-preparations.co.uk/index_broadband.htmThere are a few companies in the USA whoa re reputedly very good too - Wedgeparts come to mind = http://www.wedgeparts.com/Also try this link to the "World Wide Wedge" and their list of suppliers http://www.team.net/TR8/Finally try this forum run by another Club Triumph member http://www.forum.triumphtr7.com/There's something for you to be going at. :)As it happens I am reserching brake options and will be at S&S tomorrow but I will be looking for a new set up in line with th car's rally homologation papers as I intend using the car in competition.Good luck and enjoy your 7 Link to comment Share on other sites More sharing options...
Malcolm Posted December 12, 2004 Share Posted December 12, 2004 TR8 rotors (disks here in the UK) can be fitted without modification. They aren't much of an improvement on the original set-up though and are getting very rare, here at least. The 2.8 Capri set-up is quite common as you can still get some nice disks for it (I had vented/grooved Tarox) and pads. I believe spacers are needed to fit the Capri set-up but also bought mine as a kit from S&S.Malcolm. Link to comment Share on other sites More sharing options...
csopelario Posted December 12, 2004 Author Share Posted December 12, 2004 Thank you to both of you!Qs: So the TR8 rotor fits - must the caliper change also? (Is the rotor any thicker than the 7?) Either way, can the TR8 claiper be easily adapted?Capri 2.8 huh... I will look more into this.. I hope Shiping is reasonable through S&S.Thanks again!--Cat Link to comment Share on other sites More sharing options...
Raider Posted December 12, 2004 Share Posted December 12, 2004 On the TR8 side - the caliper used is a four pot one which bolts straight on but check with Ellis's projects for more advice.I don't think the standard caliper will work with it though Link to comment Share on other sites More sharing options...
TRishaTR Posted December 12, 2004 Share Posted December 12, 2004 A relatively new development is the 'rotor' disc - these are not round (as such) they have s 'wavey' edge which allows the disc to cool quicker as they 'scoop' air.They do, apparently, a disc to replace the OEM setup of the TR7. Reports I have had (though not fitted to a TR7) have been encouraging and have generally been felt to give better stopping performance than groove and cross-drilled (or dimpled) discs.May be worth investigating further - have a look at Rotor Discs Link to comment Share on other sites More sharing options...

But usually int he US, we call em Rotors and/or Disks. They are one int he same... but that company has them shaped (engineered) to a shape that looks very much like go-Kart and some motorcycle brake disks (or rotors)... Sweet info.Thanks,--Cat Link to comment Share on other sites More sharing options...
Raider Posted December 14, 2004 Share Posted December 14, 2004 I'll just pick up on this thread to ask a question of my own.Paul/Ellis and anyone else who has experience of these set ups.When you have fitted an S&S vented set up or TR8 brakes or one of the other options - have you found a need to fit an uprated master cylinder? Link to comment Share on other sites More sharing options...
Paul S Posted December 14, 2004 Share Posted December 14, 2004 I've got the Capri 2.8 front brakes on mine (I happened to have a 2.8 Capri on the drive) so all I had off S&S were the adaptors. Still running the standard master cylinder with no probs, I've also taken out the limiting valve to the rear brakes, but still running the std 5 spd 2.0 rear wheel cylinders. Found this set up spot on, if a little tail happy on the loose, but that's how I like a car set up. With time I'm planning on fitting a bias valve in the rear line to fine tune a bit (probably the same time the car gets a hydraulic hand brake too ;D ). If I went to 4 pot calipers (capri are M16-2 pot) I'd probably fit a larger diameter master cyl otherwise pedal travel is likely to be a bit too long for my liking-that's one for the future though (he says remembering the 4 pots sat in the shed.. ;) ) anyway...

TRishaTR Posted December 14, 2004 Share Posted December 14, 2004 I did fit an uprated Master Cylinder when fitting the Capri disc... Initially I had just the standard cyl, but after a week or so decided to fit the uprated version and felt that braking/effort req'd was much improved. Just my opinion though.

TRishaTR Posted December 14, 2004 Share Posted December 14, 2004 One other thing..... If enough people are interested in the rotor discs I am hoping to set up a bulk buy. Please check my forum for more info in the next couple of days. Link to comment Share on other sites More sharing options...
mikehardwick Posted December 15, 2004 Share Posted December 15, 2004 If anyone is thinking of an uprated master cylinder, the one to go for is from the LD Sherpa commercial - the long wheel base double wheeler, with the earlier 2 pipe output, as opposed to the later three pipe. Get it with the servo attatched, I'm told it's a bolt-on fit to the wedge, and significantly improves braking whilst lowering pedal effort. This mod has been discussed - and recommended by those who have tried it - on the TR Register forum. I intend to give it a go - to suppliment my Capri discs and calipers - in the not too distant future. Link to comment Share on other sites More sharing options...
Ellis Posted December 15, 2004 Share Posted December 15, 2004 Quoted from Raider I'll just pick up on this thread to ask a question of my own.Paul/Ellis and anyone else who has experience of these set ups.When you have fitted an S&S vented set up or TR8 brakes or one of the other options - have you found a need to fit an uprated master cylinder?Mine is still running the original master cylinder and works fine. The vented Capri setup does require a hub adapter, but the calliper bolts straight on (just needs a different brake pipe to connect). I've heard a good upgrade of master cylinder is none other than one out of a Leyland Sherpa. No experience of this myself, but from what I've heard it can work wonders even with the original TR7 setup !!! Might be worth a trip to the breakers !!!

Raider Posted December 28, 2004 Share Posted December 28, 2004 Well I have been doing some research of my own.Attached is some info I have been getting together - the dimensions for the TR7 and works brakes are from the original homologation papers so they can be taken as accurate.What I find rather interesting is the MG and Rover group discs that are available from Mintex - they seem very close to the TR7 and rally specs. The disc for the 220 Coupe looks particularly interesting.Anyone know if any of these are OK?I have e-mailed a couple of companies for information so let's see what turns up.Rimmer Brothers brake kit 2 seems favourite for me at the moment tho - a vented disc with TR8 (Ambassador) 4 pot calipers which are made by AP who made the works set up.

Malcolm Posted December 28, 2004 Share Posted December 28, 2004 The Ambassador 4-pot set-up works well. My competition V8 FHC has one (with a standard master cylinder) and it is a considerable improvement over the Capri brakes I had with the V8 DHC. I can lock the front wheels much more easily ;)FYI. Is isn't what the TR8 had as standard though. That was still two pots and solid disks.Malcolm. Link to comment Share on other sites More sharing options...

Malcolm Posted December 29, 2004 Share Posted December 29, 2004 That's the problem with buying a modified '7. Though the last owner did the build himself (car was originally a standard 2L 4-speed) the receipts are only for the new items. The 4 pots are BL Princess/Ambassdor and the disks are vented, but as to the exact type....??Malcolm. Link to comment Share on other sites More sharing options...
Raider Posted December 29, 2004 Share Posted December 29, 2004 Probably Capri?If you take the measurements - diameter, thickness etc we can probably identify them. Link to comment Share on other sites More sharing options...
Tim Bancroft Posted December 29, 2004 Share Posted December 29, 2004 Very interesting thread this- still not clear what is best- seems like Ambassador/Princess brakes?BTW Nutter- no go on secondhand brakes please!What is Steve in Croyde Bay fitting to his TR7 V8 rally Rep? Link to comment Share on other sites More sharing options...
Raider Posted December 29, 2004 Share Posted December 29, 2004 Steve is lucky enough to have the works set up already on his car as it was a preproduction genuine TR8 I believe.Front runner for me at the moment is the Rimmer Brothers brake kit 2.A vented disc with 4 pot calipers - not sure of the origins but probably Capri discs with Ambassador calipers. The kit is still available for £464 :o - exactly the same price as S&S vented EBC disc with a large 2 pot caliper.I have been given a pair of struts with big brakes and calipers (TR8 possibly) by the guy who I bought the Sprint engine off but like you Tim - only new kit in this area for me. A second hand engine is fine, if it packs up I slow down - if second hand brakes fauil i don't slow down and that's not what I want! :o Link to comment Share on other sites More sharing options...
