Fitted bigger brakes to the front of my 4x4, drove it for the first time @ the weekend and it "seems" like the ABS is cutting in early, i don't know if there is anything else i should do to the car, or is it simply a case of bolting on the new discs and calipers???
I obviously realise they will make the car stop quicker but, it seems like it's not slowing down enough before the pedal starts juddering like hell.
The thing is, the ABS was fooked when i took the car off the road, but now i think I've fixed it by fitting new sensors, so maybe I'm just imagining it???

Jay,

it happens mate the system is setup for the 285mm discs ect so withthe extra leverage with bigger didcs baffles the abs

you are still braking as you would with the noral stoppers fitted

because the brakes now require less pedal pressure to provide the same stopping power it's just a question of you gettin gused to the pedal again

does it flutter really softly ordoes it kick in really harsly as there are 2 very distinct modes of operation, the soft flutter is normal, the heavy kick back is slamming the anchors on

exactly same issue the previous owner had on my car that why i hvae a switch fitted to turn the ABS on/off as i wish, but yes you are correct mine also kicks in at low speeds

Ah ok, that's good to know then, I haven't broken anything!
Yeah it just does it softly at low speeds, I was just driving the car 50 yds or so up and down the street to test the brakes so I didn't go very fast, as I've not had it out on the main road yet.
Thanks alot for the help guys, car is very nearly finished, it goes AND stops now!

with the 4wd versions there is also an extra relay in the ecu to limit the amount of lock so as to preserve the transfer box and viscous coupling so the braking is set up differently

Ok, that's even better advice than I could've hoped for!
Maybe I should just PM you infutire instead of posting...?

just think of all the people that sit glued to pf during the day because there is nothing else to do or any other sites to visit via the ocmpany server that you'd be letting down

at least your abs works!! where did you get the sensors?

rog

iTrader: (2)

It's never worked since I got the car, I got them off of Ebay cheap cheap i think i paid £20 posted, i think it was off a 2.0DOHC 4x4 or something, they were minted!

wow thats cheap!

so are all abs sensors the same on other models then?

rog

iTrader: (2)

IIRC yeah they are the same or similar for most Ford 4x4's BUT the 2WD system is different, the ABS control unit in a 4x4 is a specific 4x4 system but I don't know if the sensors are differenet aswell, i couldn't say for sure what you would need, I'd be VERY surprised if your setup was specific to 2 WD cossie though. Always a good thing to know what common parts are used on other cars, saves you paying a premium on "cosworth" stuff.

all the sensors on all the seirra's are the same

as in the fronts are the same and the rears are the same, but you can't put the rears into the fronts as they are a different shape and vice versa

the differences start when you swap between the granada stuff as this has a higher sheidling to stop electrical interferance as the granada's had more electric goddies than the seirra's did

from memory it's soemthing like 104/5 for the sierra and 112 for the granada but i have no idea what the numbers mean

the problems start if you swap them over on the granada's so they shouldn't have any problems the other way

you get the same sensors in the escos but the big difference is teh puilgs that go into teh loom are different, as are the oens on the 92 spec onwards granadas as well

and swapping them is a bit of a no no as i've yet to find someone who's succesfully done this

the other problem is that they rot into the hubs, and when you pull them out they snap, so be warned
