Mk2 Cortina gurus? Or any Contina gurus

Have a 69 mk2 cortina and was looking at upgrading the front calipers! Apparently the MK5 bolt straight on and give a bigger braking area! Anyon e done something similar or know if they do bolt on!

Cheers Jase

austin princess were the ones you want! unfortunately very hard to find now!

Jason - how thick are your existing rotors! 12.7mm or are they the early thin rotors and small calipers!

jason18, Mar 17, 6:27am
Hey UJ. The rotors I couldnt tell you as car doesnt get picked up until friday. Its an original car and the calipers did look very very small and felt like they hardly worked

Bump for UJ

There's no power booster on a Mk II - consider adding one of those first!

sr2, Mar 17, 8:18am
Fitting a booster will not improve the efficiency of your brakes, all it will do is reduce the amount of pedal pressure required to operate them. Sure, and particularly with upgraded brakes ( UJ is the guy to get advice from) a booster is well worth considering but if you need more stopping power you need to fit better stoppers!

Some Mk2's came with booster. Usually GT, GTE and Lotus though. Don't Mk 5's have ventilated discs so they would be thicker! Like Francis said above the Princess 4 pots were the ticket but why don't you try Enford in ChCh!

pretty sure the threads for the brake lines are different. TRIPLE check them. I know i had issues upgrading the drums on a MK1 escort to MK2 sport brakes because the threads were different. i think i had custom brake lines made.

sr2, Mar 17, 8:55am
From memory I'm fairly sure they never made a Cortina with ventilated rotors. There is a Capri ventilated rotor that will fit but you obviously wouldn??

saki, Mar 17, 9:11am
they require some effort,my GT has the bigger calipers(p16) mk3 has the same size from memory but calipers are metric, p16 imperial m16 metric.

try fitting japanese front end nissan toyota mazda even ,had a mk2 cor yrs ago wasnt impressed with it over all for a gte model even souped up the motora laearning curve

sr2, Mar 17, 8:09pm
I did a little Goggling on the subject last night. Yes it appears that the ventilated 2.8 Capri discs are a bolt on but finding calipers will be a challenge; Grenada, Volvo and Princess Calipers are as rare as rocking horse poop over here. I??

unclejake, Mar 18, 12:30am
A Mk2 Cortina usually had decent brakes from factory. I used pretty much standard Mk2/Mk3 brakes on my Mk1 Cortina (race car) and could brake 90 meters out from the Pukekohe hairpin doing around 200kmph (I think it was 90 meters, it was a while ago so perhaps it was 110m!). I didn't have a booster but did have a tandem m/c (out of a Corona of some type).

The pedal will feel leaden to a driver not used to un-boosted brakes. You could fit a booster to the front brakes only if it really bothers you but perhaps spend a bit of time driving the car first.

The Capri set-up has the same rotor diameter and friction pad area as the late Mk2 or Mk3 Cortina. It is only an upgrade if you are cooking the front rotors you have. The Capri rotors are very expensive.

The guy I would turn to for a performace brake set-up on a small Ford is Les Hunter in Christchurch. leshunterauto.com

Cheers UJ. Yeah my mate use to driving later model cars. Altho it did seem hard to stop aye when I drove it. Maybe he should look at getting rotors skimmed and fitting a top quality pad! What does the tandem M/C help with!

saki, Mar 18, 3:23am
you could try a smaller diameter mastercylinder I will do some homework out in the cave from memory there are 3 different sizes.

saki, Mar 18, 4:02am
Jason a bit of techo information
up to sept 67
disc dia 9.5
total pad swept area 171.9 sq in
from sept 67
disc 9.625
swept area 171.9 (smaller pads I would say)
master cylinder sizes
.625
.7
Mk3 all
disc 9.74
swept area191.87 sq in
I would be on the look out for MK 3 on wards later models my have even more pad swept area, try some softer pads or push harder they do pull up rearly wwell.

A good web site BSC Cortina

unclejake, Mar 18, 5:16am
The tandem M/C is just a saftey feature. It does not improve braking performance. I used Mk3 Cortina rotors and calipers. The rotors were 247mm o/d and 12.7mm thick (from memory) but I used to turn them down to 242mm O/D to assist in pad locator pin clearance. You may not need to turn the rotors down for a Mk2 which makes it a bolt on conversion

You quite possibly already have these rotors and calipers on the car Jase. A photo of the caliper will tell us.

Saki, the UK and Australian Cortinas were different to the NZ ones in a few ways. Your info (above) looks pretty sound but a NZ reference source has never been written to my knowledge

jason18, Mar 18, 5:25am
Ok cheers UJ. I will see if my mate can send a pic through tonight. Will get back here soon to let ya know,

unclejake, Mar 18, 5:33am
He will need to take a wheel off to get the photo, but it is a Cortina so give it time and it will fall off anyway.

Get a photo of the driver's side engine bay too. That will help identify the M/C

unclejake, Mar 18, 5:51am
Oh, SR2 - just for the record: The 2.8i Capri rotor conversion uses a standard Mk3 two pot solid rotor caliper with a spacer inserted between the two caliper shells. The spacers are easy to get but the rotors are about $180-250 each.

As you rightly assumed: The brake conversions one can read about online are done in Australia or the UK using parts from models that are easy to find in those countries.

saki, Mar 18, 7:15am
UJ I dont have any info on aussi brakes but cars assembled in NZ had the same brakes available to them as the uk models, struts came into the country fully assembled wtih discs and calipersI even noted in the wiri parts storegroup 4 BDA .bilstien struts complete with alloy hubs discs and 4 potters probably about 10 pairs.

unclejake, Mar 18, 7:40am
Godbless the mighty Ramflo filter.

You have an unboosted tandem M/C. The caliper photos are great but my memory is failing so I need to have a quick look at my photos before I can be confident about which ones yours are (I think they are the later ones, either P16 or M16).

Goose13 would pick them in an instant

big.b-lil.c, Mar 18, 5:08pm
you are in luck go to "the transmission magician" talk to nelson Marshall, he races a capri and relay knows his stuff on old fords i spoke to him bought telstar rota's and discs on a capri a few years ago.
