Hi, am looking to put a standard disc straight onto the back of my escort and use 4pot calipers. I've heard the st170 front discs will fit but I'll have to machine the hub for them to fit over.....and ideas? Cheers

 

I have st170 items on mine I just took some off the caliper an made me own brakets
cost me 40 quid all in

they fit straight on the hub its the carrier and caliper you need to take few mill off ,don't see point in machining the disc like most do as you have do it everytime you change them

 

Cheers, I tried the the standard front escort ones on and they never fitted over the hub, for some reason I thought they would be the same.... I'm putting on billet 4 hi spec calipers on......that's cheered me up...I'll get them ordered, ta

 

got mine off ebay for 19 quid discs that is

 

Well that will do me very nicely.

 

Any pics of these fitted.

 

Loving the work light Dingla
thanks for the pics aswell

 

See above mine are 300 mm

 

It's good isn't it lol

 

So are these the st170 front discs? and are they 300mm in diameter? Are they fitted to an escort cosworth?

 

Yes and it's a focus cosworth running escort cosworth running gear

 

What have you used to space the caliper from the bracket, looks like blue tube in the pic, obviously I take it it's a piece if metal tube painted blue? What length is the spacer? also what thickness is the st170 disc as apposed to the 4x4 rear disc where it mounts to the hub face, does it push the wheel out or require longer wheel studs ?

 

Think it's 14mm but unsure as car 250 miles away
At the min you need make mounting brackets aswell
Flat plate with holes in il dig you some pictures out tomro

You sorted any measurements mate, also what did you use to space the caliper from the bracket (blue tube)?

 

FORD Focus
2.0L ST170
2003 On

Front
Protex Disc Brake Rotors
Quantity Supplied = 1 pair
DR2101
Vented

Diameter: 300
Overall Height: 43.5
Original Thickness: 24
Minimum Thickness: 22
Centre Hole: 63.5
Stud Holes: 4

They say 24mm thick did you have to do anything to the calipers to get them to fit? As i thought cosworth std rear disc,s are 20mm thick.

 

You have to tak a few mm off iinside of carrier to accept disc
And make brackets to hold caliper in new position

 

the blue part is tube tured down to 14mm If I remember and as dave says you need take some off the carrier ,my car is with ^^^dave above if you need some measurments

 

I'd be making the brackets a minimum of 8mm thick tho to reduce flex

 

Did you have to make longer brake lines? Also does the handbrake cable still fit ok and clip into the rear arm brackets like normal?

 

Have the calipers also been modified? Or do they still fit the thicker discs, even with new brake pads?

 

Well I've got mine fitted, I'm just having some brackets possibly laser cut depending on price, may be able to offer a kit,

 

A kit would be Ausome

 

I will buy the kit happily pal!! Get them made

 

A kit would indeed be very nice!

 

can see how easy the plate is to make on mine here 14mm spacer and some machining on the caliper and carriers

 

Cool mod that Dingle.

 

I think Coswurv is offering a kit over on the escortcosworth forum, using laser cut alloy brackets.

 

Not meaning to sound stupid so apologies if it is, but isn't the pad only touching like half of the disc?

 

Yes it does, but all 300mm set ups that use the original caliper are the same, unless you buy bells and rotars. Best way to stop any corrosion in the unswept area is to mask it up and dust over it with some matt lacquer.
