Are there someone that on a mk4-5 has replaced rear brakes with two discs? From which car do you take it? The rear disk of a focus are too much big for the original alloy wheels? how many euro did you spend? I'm going to take in a car demolition all the necessary...if I find it!

the escort mk5 is from 90 to 95?
the GTI disc are the same?The support on the suspension are the same?
Why 2 valves?on the rear axis don't arrive only a oil tube?

When doing the rear drum to discs conversion you need to setup correctly the oil brake pressure to the rear.

For example:
Your car on std brakes (discs at front and drums at rear) 70% front and 30% rear. Now if you exchange drums for discs your car is going to start braking too much at rear... say kind of 60%front 40%rear... or even 50% 50%.
Rear wheel will lockup and you loose control of the car... not nice. :(

You need to restore the brake balance.

other thing... you only need discs at rear for two things:
- looks
- if you go too high on engine power and you attend trackday events. This way drum brakes may not be up to the job.

Usually drum brakes are more than ok for anything uprated to 200bhp with trackdays. Front discs is the thing to upgrade!

my fiesta has only 75 cv...but I don't like its brake.
Now it's has 30000 km and is nearly necessary to replace front discs and pads!!!
Some time when I brake, the brake don't satisfy me and I have quite fear!
Therefore, I am inquiring on how I can resolve the problem:I'm thinking that if I upgrade the front disc, the car, during a brake, stop too much with the front disc or not?If I replace the original discs with 2 discs and calipers of another ford, is it sure that they enter in the original alloy wheel?from which ford can I take compatible (with the hubs) discs and calipers?

no, I have 14" wheels with 185/55 pneus...it's difficult in italy to have the 15"...only the zetec-S are them and on the 1.2 is difficult to have the omologation... :cry:

Go for ZS front setup... you won't regret it :) I'm running mine in at the moment (I have 100 kms on them) and they seem to be much more effective than the standard setup (even the 240 mm vented). I haven't given them death yet so I do't really know how well they perform when hot and how prone to fading they are, but they feel very good at normal operating temps.

As said b4, upgrading the rear to discs isn't really worth it unless you're running a monster setup at the front and need the extra braking power at the rear to restore the brake balance.

If you have you mind set on it anyway, take into consideration that the Escort uses 270 mm discs at the back, which probably won't fit under 14" wheels. Apart from that, I think the hole pattern on the mk5s rear beam isn't compatible with the Escort hubs. I'd say your best bet would be going for Focus hubs, discs, calipers and pads.

what had you to change beyond discs?the calipers I think that are the same, but I'm not sure that the support of the calipers (and therefore the part that is crossed by the axle shaft) are the same.What did you change?how many euro did you spend?Are the pads original or of another constructor?

I got ZS calipers, pads and discs... they bolt straight on to the original hub so its a plug and play conversion. I used Brembo OE discs and the pads are of unknown origin... all I can tell you is that they have "TX" stamped on the sides, but I really don't have a clue about the manufacturer...

Note that I also have braided brake lines and ATE TYP 200 brake fluid, which made a nice difference with the standard setup, but hopefully will be coming into full play with the bigger discs once everything is properly bedded in.

If you are considering doing that conversion, I advise you on getting 2nd hand calipers (as I did). The ZS is a relatively new model so the calipers will probably be in perfect condition (unless they have obvious signs of cracking or something like that) and it will bring down the price of the setup.

Good but I thinked that you used original zetec-S discs.I think that with the Brembo disc and pads not ford, even if the disc are of 240mm, the brake is more good... :D

Now I don't understand:do you change only the brake fluid or do you do also some other thing?

the problem is to find it!!!Do you believe if I tell you that in all my life in Italy I saw only 3 zetec-S???In a demolition car is more easy to find a good jaguar... :cry:
The 1.2 16v's calipers aren't good? :?:

Nope... 240 solids. But I had 240 vented during some stage, then got back to solids due to popular request :lol:

Regarding the Brembo issue, they are just regular OE fitment discs, so I don't think they should be much better than Motorcraft items... I just bought them coz they were cheaper.

You can get calipers from Puma Speed (www.pumaspeed.co.uk) at 60 pounds a pop plus carriage... which means the pair shipped to Italy should cost around 200 euro or so. Or you can get it as a complete kit (calipers, discs and pads) for around 170 quid plus postage. Drop Tony a line... he'll sort you out.

I changed the brake fluid and the brake lines... the little rubber tubes that go from the solid line to the caliper :) I used Teflon lines (steel braided, Teflon, whatever you want to call them) and it made quite a difference to the pedal feel and the way the brakes handled the higher temps even with the standard setup.

I hope this helps to clear up the issue... feel free to ask anything else you want... we're all here to help.

We here in Portugal, have exactly the same problem! :evil:

There is a thing I don’t understand?  :x If an mk5 ZS as the same base as the mk5 1.25, what is the problem?  :evil: There are sh”@£$%&ts I can’t understand! :x  :evil:

What can happen in Italy if you have 15” wheels mounted in your? They confiscate the car? Or they only pass a ticket? :?:


In Italy, the mk5 zs has the 15", the zetec the 14".If I want to put the 15" under my car, I had to ask a (technic)autorization to the ford and after I had to pass, with the new wheels, a revision of the vehicle...
If I put the wheels without revision, The police, when it stop me, do me a fine and seize the vehicle...it's a absurdity!!! :evil:

100 for the pair. Note that we're talking about Brembo OE discs, not Gold or Max.

NM, all mk5s are supposed to run that brake setup as standard... except the Power Discs, obviously ;)
