ABS on FRP Rear axle

[ethanfitz]

OK so here it goes....

My new Puma (standard 2001) has a Racing Puma rear axle with rear disc brakes, but i think i have no ABS? basically i want to know (if any one can help me) how and what i need to get to put ABS back on the puma...

Firstly off i need to identify what i have so (warning NOOB part coming) can anyone tell me/show me what im looking for an where, to identify any ABS components?

Secondly what do i need worst case if i have nothing left of the old ABS system:

also is ABS on the front and rear?

sorry for the NOOB question but i have no idea but i do want ABS to work... you know ... just in case...

thanks for all the help from previous questions and in advance for this one... PS... all will be unveiled soon about my New Puma .....

hi, you need a pair of new original abs sensosrs ( they come as one left and right) and puma rear abs tone rings

then you need to expand the hole in the stub axle to acsept the bigger puma abs sensor, and you need to take down the hub to acsept the puma tone ring. if it is a genuin frp axel, all you need is to replace the abs sensors.

there is a guide in the pumapeople.com wiki section

Thanks cartman (your becoming the go to guy on all my topics :lol: ) ...

so if it is a genuine frp axle do i still have to get the rear tone rings and do the mods... or should i just be able to buy this:

do i need more things as well ... sorry but i have no clue about ABS (here to learn i suppose)

thanx

If it is a genuin axel, chanses are the tone rings are intact, the abs sensor you have found on ebay looks correct

hope this works :=)

All Focus / FRP Comment
Beware with any of these options that the rear disc setup will extend the track of your car by 11mm*. If you are already running 20.5mm spacers, you will probably want to consider changing for smaller spacers. I have changed to 12.5mm spacers and so far things seem ok.

To make your ABS work with this setup you will need to enlarge the ABS sensor holes in the rear hub, and tap a new hole for the sensor mounting screw. You will also need to use the Puma's ABS tone wheel, this is a slightly smaller diameter to the Focus item, so the hub needs machining in from to reduce the diameter to fit.

I understand the most difficult issue is getting the spacing right between the sensor and the tone wheel, which should be 0.6mm*. While the FRP uses an Escort estate rear ABS sensor, having compared that with standard, I don't really see why you couldn't use your original Puma item.

If you are considering upgrading to Focus or FRP rear discs, you will need the following;

2 x hubs
2 x spindles
2 x callipers
2 x calliper carrier
2 x splash shield
1 x suitable handbrake cable, FRP is ideal, I understand Focus will fit but will need to be fully tighted on the adjusters, or possibly Fiesta ST, though as far as I know, no-one has tried this yet.
2 x suitable brake lines, again FRP is ideal, but Puma standard front lines can be used.

Of course you will also need;
2 x brake disc
4 x brake pads
The beauty of using Focus parts is that the consumables are excellent value. With any brake conversion, I would generally try to use new consumables wherever possible.

To make the ABS work, you will also need;
2 x standard Puma ABS tone wheel FINIS 7314843, circa £6 each.

You can also see that there is a larger machining operation to allow the FRP sensor to sit slightly further in;

it did not. here is the link to where the pictures are

thanks a bunch man :grin: guess ill sign up to pumapeople too then :lol: should finally be getting my coilovers sorted this week so can start on the ABS soon :twisted:

Do your abs/traction lights stay on permanently then,or go of straight away???

 

[Cartman]

Hi, didn't catch your question about finding out about ythe rest of your abs.

Ok, so e abs is a few components, a sensor at each wheel, and a tone ring on each wheel, a pump in the engien bay, and pfcourse the light on the dash. When you start the car the 2 yelow lights on each side of the dash wil light up,one says abs, the ogher is a tyre. These shal then go out if the system is ok, if they stay on, there is a fault, to figgure that out, unles it is obvious, you need a code eader, to se where the fault is.

Hope this helps

 

[ethanfitz]

i have no lights on the dash for ABS or tyre...

 

[Cartman]

it's a 1.4 right? I do belive you could buy te 1.4 whitout abs, but it may just be that the bulbs and or fuse has been removed. I don't have a users guide, so I don't know what fuse the abs is, but if you do, you should atleast chek it

also If you look under the hood, you should be able to se the abs pump.

looks like this

 

[ethanfitz]

nope its a 1.7 (im selling the 1.4 now) the previous owner upgraded to rear disc brakes on a frp rear axle... i will have a poke around the engine tonight to see if i can find the pump :lol:

 

[ethanfitz]

bingo found the pump this one yer:

all the fuses are ok... i just dont know what he has done to disconnect it when he changed to disc's and the frp axle at the rear...

its in a garage today to sort the suspension out so ill ask them to have a look...

 

[ethanfitz]

Alright, i got back form the garage suspension is good now raised about 25mm (1inch ish) and i would say it looks better as if the wheels fit properly and are not tucked in like before... also ride is much better :thumbs:

as for the ABS the guy in the garage said it looks like its all there and it looks like its all fitted good as well k: so good news ... but why dont i get any lights on the dash ....

do you think these could have been removed? how do i get to them to find out?? and what bulbs do i need to replace them with if there is none there?

 

[ethanfitz]

Small update: Of course mr BOTCH JOB BILL who had this car before me melted the LED's for the ABS and traction control.... off to find some clocks with similar mileage then I guess....

or buy 2 new led's and get them soldered into your original clocks. will be much cheaper

 

[ethanfitz]

that is a possibility... I think my soldering skills are a bit rusty to be accurate enough for that job.... anyone know what led's I would need? (links are always much appreciated)
