Ok so i have recently purchased a 1976 leyland s (im pretty sure.)

Anyways, it has a 998 and i realise it doesn't really need disc's but it will most probably be used as a daily so its in our best interests to give it some better brakes.

Ok so i am thinking just put discs on the front as backs don't do enough work for it to be worth the money.

My question i pose.

Will these do the job?

Also... these seem expensive to me, my evo 4 brakes for my lancer cost 750 for all 4. So is there any cheaper options that are adequate?

Thanks.

i believe there's some cheaper conversions (camira brakes i think?) that have been done before, someone knowledgable can expand on that.

i was actually wondering on this too, how much work is it to actually do the brake conversion?

they would be quite adequate and yes they are a bit expensive but unfortunately for the mini community , that is the going rate. Getting a second hand setup could prove to be costlier by the time they are reconditioned.

Yes, you can fit modified Camira brakes, or modified Honda Civic or City ones, maybe others too. However, as they are not engineered, you could be up the creek in a barbed wire canoe if you have an accident, hurt somebody, and your insurance company wipes you.

Cooper S brakes are a bolt in job, they stop well and replacement bits are all available. That Minisport price is not bad.
As said above you can buy s/h and do them up, but it's possible to spend $1600 by the time they are on the car. People here have done this.....

what sort of modification is needed on the other brakes?? extensive?? i don't really want risk that... but you could get them engineered correct?

Just a side note, if you change from drums to disc on the front you "should" change your rear wheel cylinders to (correct me if i'm wrong) 5/8ths. So thats a little bit extra money on top of the disks

http://www.minis.com.au/minis/catalog/p ... cts_id=749

comes with timken bearings and EBC pads (green or black) $1599

http://www.minis.com.au/minis/catalog/p ... cts_id=748

standard bearings and pads $1495

The other option is to source some more recent 2nd hand 8.4" rover discs/calipers. That conversion is meant to be cheaper than 7.5", although minisport kits cost a decent amount more! This will require 12" rims though, which adds to the expense!

'a mini is for life, not just for christmas!'

i do plan on changing rims, i want to get some 13's, the ones the same as the guy that has the starlet gt engine. can't remember his name off hand.

James,,, maybe if you have changed your brake rotors & pads on your evo then yes it would be far cheaper than replacing the entire mini wheel """Assemblys""", hubs, Wheel-bearings, ball joints, drive flanges, calipers, pads, CV joints etc etc... there is quite a lot involved with that disc brake kit you posted,,, not just rotors & pads

& of course these assemblys don`t come assembled, you`ll need to assemble them before you can fit them,,, & then you`ll need a wheel alignment as the wheels will be toing out after the brakes have been fitted & yes sometimes people experience the rear brakes locking once the disc assys have been fitted to the front , so a change in rear wheel cylinders & possibly the brake limiting valve is good to change also

it`s a ackage deal to do it all properly ,,, & then you`ll have great stopping power that lasts & lasts with very little maintenance needed.

You should put your heart & soul into everything you do.

The cheapest place to get 7.5 disk is Miniimports.

I got second hand one, and it's more trouble then money saved, especially if you can't do the work yourself.

As said before you will need to change the rear wheel cylinder, but not expensive at all.

Hope this help.

I used to convert Hondas to fit (some) 10" wheels but I don't do it now.
I only know of one bloke who got Honda ones engineered, and that was in Qld.
The problem with all this is there is no `type approval' mechanism in place for manufacture of these `kits'. Each single brake conversion done is at the mercy of the engineer, if you want it approved.

To fit Hondas into 10" wheels the 9.1" rotors need machining down to 7.9", and a fair bit of grinding is needed to the pad mount bracket and caliper. Also the pads need to be cut away and 1" spacers bolted to the rotors.
IMO this work would prevent approval being obtained.
However, Honda Civics will fit into some 12" and 13" wheels without these mods. They just need a caliper mounting bracket made, and the rotor mounted to the (drum brake) Mini drive flange.

ok first off its a lancer coupe not an evo.

but thats not the point.

ok so it seems these package's through some of these company is the way to go purely for legal issues and ease in installation and future maintenance.

Thanks for the help.

Spot on - by the time you engineer an alternative, you're going to be looking at a minimum of the same money as if you were to buy S discs. And, of the conversions that are common, there are only a few that look likely to get approval on a regular basis (one of which was David Rosenthal's recent conversion, which looked fantastic, but was a lot of work!).

If you're planning on going to 13" rims, buy the rims first. Then buy the 8.4" discs. The replacement rotors and pads are cheaper, they're usually no more than the same price as S discs, historically they're cheaper, and I believe they also don't require changing the rear slave cylinders..? Because of the higher braking capabilities of the bigger discs/calipers..? The main reason why people don't fit the 8.4" discs is that they don't fit under 10" rims, if you're not going to have them, then there's no reason not to have the bigger discs.

i bought some 8.4 disk breaks from the uk 2nd hand.

landed with postage for $890.00 good exchange rate & i made an offer! has new pads & stuff see description from this seller.

i check what he has time to time.

they look & work great & he sells them all the time! trusted for sure.
