Just wondered if anyone had thought about using the rear brakes off a Mondeo? Are they the same size as sierra 4x4 ones?

Cheers

Got focus rear disk set up on mine

 

Ive got the run of the mill 2wd cossie/sierra/granada ones on mine, u might find u get a considerable increase in pedal travel however which makes the whole mod seem almost not worthwhile

 

must be air in your system mate, pedal travel shouldent increase cus you have got rear disks???

hmmm this is what everyone keeps saying but i had air in the sytem before and the pedal hit the floor, so i did the remove the rear calipers and lift them up thingy, and now the brakes actually work with a little pedal travel.

In theory though you have a lot larger surface area so its going to take more fluid, hence more travel. A number of people on here have said they have the same set up also with not fantastic results?

Currently researching into bigger master cylinders.

Do you yourself have this set up?

 

Brom @ Zoo Motorsport does 2 kits


4x4 rear disc converion new or recon calipers

2wd rear set up , Also new or recon calipers

I got the 2wd kit with recon calipers,Cant complain for £250

 

ive got the 2wd kit from brom as above mate, i dont have any travel , well only a tiny bit, you have to lift the calipers right up to bleed them.
i dont think there meant to be amazing because of the load pressure valves under the bonnet, course you could always remove them if you want your rear brakes to lock up lol.

 

yeah thats what i had to do, got thos crappy brackets that mount them at 45 degrees, did that, a shitload of air came out and they actually worked after that.

Ive got 4 pots on the front too mind you, full 2wd set up.

There cant be anymore air in the system Pressure bled aswell!

Ive only got the compensators on mine, no load apportioning valves

 

ive got the brake bias valves of a 3i, (no abs) can get all four wheels to lock up (fronts go fisrt) im also still using rear drums. i was going to fit rear disks but the pedle already has crapy feel to it.

i thought that wheel cylinders in drumbs actuelly held more fluid than calipers.

is there any way i can get more feel in the pedle.?

 

the rear wheel cylinders have a lot smaller surface area than the rear calipers.

So youve got a bad pedal and you dont have the rear disks?

Its usually the rear disks that lose the feel from what ive gathered?

 

Well, after that NIGHTMARE i had with the brakes on my cabriolet, the car has been for the MOT and has passed first time, i thought they might fail the pedal travel (and i did have a little play with the nut in the servo), but it all passed. So theres no way there can be air in the system, heres the results:

N/S O/S

F 250 250
R 120 120
H/B 120 120

all good readings, and all equal, so this must conclude that the standard Escort/Orion master cylinders arent quite up to the job of the big brakes. The tester did make a comment that the front wheels were a tiny bit tight which im sure is where ive adjusted that nut, so ill be undoing that again dont want the brakes catching fire.

Even with the standard brakes though the pedal felt crap compared to my orion (brakes come on as soon as the pedal is touched), but the cabriolet always had a bit of travel, and the master cylinder was changed aswell, has anyone ever known the compensators to play up and/or break (not the load apportioning valves) the ones under the bonnet.
