Guest Cally Posted June 24, 2007 About to buy a 205 with an mi16 conversion. However it still has the rear drums so I am assuming it has 1.6 brakes still on the front. Is it possible to change to a bigger caliper or do you need to change to a 1.9 hub? If changing to a 1.9 hub what else needs changed? driveshafts? Whats the best way to tell if it has 1.6 or 1.9? The guy was unsure as the conversion was done before he bought it (done at ecosse) would they upgrade the brakes when doing a conversion? Share this post Link to post Share on other sites

Baz 421 Posted June 24, 2007 The simpler answer would be to replace the calipers with 1.9 items, anything more would need hubs/discs etc changing. What's wrong with 1.6 brakes though? They're good if they work, not too old worn out etc, and a lot lighter than the 1.9 versions. Share this post Link to post Share on other sites
Jrod 7 Posted June 24, 2007 Basically nothing will fit 1.6 hubs. You can either swap for base model hubs and continue to use 1.6 shafts or go for 1.9 hubs and use 1.9 shafts. Share this post Link to post Share on other sites
Guest Cally Posted June 24, 2007 how much would it cost me to swap to 1.9 hubs etc then as I want to fit a bigger brake setup due to being a bit worried the 1.6 ones wont be upto much on track. Share this post Link to post Share on other sites
Jrod 7 Posted June 24, 2007 Hubs will probably be about £15-20 from a scrappy. Then the price of new calipers and discs. Share this post Link to post Share on other sites
Baz 421 Posted June 24, 2007 I've driven both std 1.6's & 1.9 brake setups on track and had no problem. I was actually very amazed how well a 1.6, just with 1.9 calipers, decent pads and fluid performed at Donington a few mths ago. No problem with them at all. I'd say pad choice and decent fluid, and perhaps some braided lines wouldnt go a miss. Share this post Link to post Share on other sites

(I assume you meant the discs and hubs were 1.6) I have the std 1.6 setup with goodridge hoses, mintex 1144 pads and comma 5.1 synthetic fluid. The work was done a while ago and now I need to change the fluid, master cylinder and handbrake adjuster, but I'm sure I used to get fade when it was all fresh?

Guest Cally Posted June 25, 2007 I will probably upgrade the hubs so I can still use 1.6 shafts then get bigger brakes and stainless hoses. Whats the best / easiest to get a hold of? 307 HDi? Share this post Link to post Share on other sites

Indeed, all std 1.6 running gear, just with the 1.9 calipers, the calipers are just a better design in most opinions, they work well, have more feel and a better bite. Just with an extra weight penalty. It wasn't my car, but iirc the discs were fairly new and the pads were Ferodo Premier's/DS2500's, fluid wise, i think just new Dot4, and i don't think it has braided lines. It was driven pretty hard round Donington not a particularly hot day, and i was pretty hard on the brakes, and the owner even harder understandably, and neither of us suffered any fade, as i said, i was very surprised at it, changed my mind about std brakes anyway. I know a few people running similar set-ups with no problems either. Previously i'd driven one of my cars round Combe, with basically std but recon'd 1.6 calipers, probably a good few K miles old std discs and pads and god knows how old fluid, they worked well for the first few laps, until heat got to them and i discovered serious fade trying to brake down from about 100! But i'd put this down to the old fluid. I can't see why you'd have issues with your set-up though, sounds like they'd be not too bad to me, obviously depends on how long you're out on a session, what braking for the circuit needed, limitless different factors really, i can't really say.

Yeah thanks baz. I'll get the problems sorted first, then decide if my setup is good enough or not- I have to put a stop to the spending!

24seven 104 Posted June 25, 2007 I've some EBC greenstuff pads on the front of my 1.6, and it stops pretty damm sharp! I wa gonna do the whole 1.9 beam swap, and 1.9 hubs, calipers & shafts too in preparation for my Mi16, but decided it's not really necessary. that said, my car is completely stripped out back from the B pillar, and there's a fair bit gone from in front too.
