can anyone help me, ive got a problem where as every second or third press of the brake pedal and me red brake warning light and abs light comes on, with this something runs as engine dipps in rpm, any ideas????
cheers joe

 

could be a dodgy earth mate, didnt you say you had problems the other week ?

 

sorted my cristmas tree lights in middle dash but this problem has been with me since i bought the fucker last year

 

sounds like your using the brakes too much mate, you up the garages tomorrow ?

 

take it you've checked the obviouse like fluid level and then the brakes arent siezed and work ok?

could well be a switch or dirty sensor. perhaps wheel sensor for abs as the abs light is coming on?

 

paul mate spent 5 hours earlier.

phil focus - fluid is fine and the brakes have been changed , i changed all the relays under glove box for spares no joy, could it be pressure switch on brake unit itself??

 

i'm not very knowledgable about the electronic side of braking systems but this problem does sound like an electronic wiring/sensor fault or maybe even dash light fault...not ruling anything out here

if there is a pressure switch then maybe that.

 

Didn't your brother keep the abs units and ecu from his saph?

Try one or the other until you find the fault. Can't see it being a wheel speed sensor as that would bring the light on as soon as the ignition is switched on and will stay on or bring the light on as soon as the car moves if one isn't reading.

 

gary i have another pump unit, ecu and distribution block, just waiting for you to come and sort it

 

Just try the ecu first, it's the easiest to do just on top of the engine ecu on the bracket.

If that don't work, there's a pressure switch on the main pump. Just swap that over, if you don't want to do that, just swap the entire unit over, piece of piss to do. Same as the valve unit on the n/s inner wing, pretty easy.

 

How many ABS relays have you got behind the dash? I could understand and explain your issues if it's got a later 4x4 ABS loom with 3 relays, as opposed to the earlier 3 door and 2wd saff ABS looms with 2 relays.

 

Sounds like a failed relay ..... would test them first ....... buddy

 

its a 2wd, yesterday i changed the pink relay, green one grey one and a 70amp black one, no joy, as said above think im gona move onto abs ecu and brake unit itself...
