ABS problem?

[TiddlesRX7]

Can anyone help me out with a ABS problem. Intermittantly the light keeps coming on the idiot cluster. The brakes are good and solid except just before the car stops. Like pulling up to a junction the brakes are good then just when I dip the clutch to stop I can feel the ABS working (juddering feel). Then I can hear a hissing sound from under the bonnet. I also am getting alot of squeeking from the brake pads at the moment. Anyone know what it is.

Have you bled the ABS pump?

[TiddlesRX7]

Nope. How do I do that then?

There are 2 bleed screws on the top of the ABS unit, its the last bleeding point in the run to do, just don\'t look over it when its being bled or press the pedel loads as you get a HUGE fountain of fluid shooting straight up lol

My ABS is being spesh as well, its not arming anymore, so it might be a sensor that has been caked in brake dust, try the bleeding first though

So its just a case of cracking the bleed screws untill I get fluid. No pedal pumping before hand or anything? Cheers Mitch

You need to bleed it as if it was a 5th caliper

Hmm Ok. I\'ll give it a whirl tomorrow.

ahhhhhhhhhhh this post !!!!!!!!!! LOL ( private joke between me and ade - no wonder i couldnt find it - thought you might have updated it )

if your abs is working ( in a fashion ) then i dont think the ECU is at fault - if the ecu is dead then the ABS light stays on all the time - and the ABS doesnt work at all

so could be the pump is on the way out ( just ask mazda for a quote - they are about £1500+vat !! )

im not sure if you can flip the seals in the ABS if you use an assisted bleeding tool - so might be worth a research on that if you can

but i have a complete abs pump in the garage if you believe yours is on the way out

and i know this sounds really really silly - how is the fluid in the car ( old , new , full , low ) and do all the pads have a load of life left in them ?

or if the pads are fine - what are the dics like - they got loads of meat still on them ?

[TiddlesRX7]

Pads are well not the best shall we say. Disc\'s I think are ok but will be checking over the weekend. I have some trackday/fast road pads on order with MRP so hopefully that\'ll help. It would be nice if it is just pads. The squeeking is really bad now and annoying!
Bleeding the ABS pump hasn\'t helped.

Before my car was taken off the road my abs was suffering from the same sysmtoms as yours.
As im putting braded lines on my car im taking the abs out allntogether now.Ive heard its a fairly simple removal though.
So ill have a pump up for sale.

[grinder]

you can borrow my pump if need be mate - or as adam suggests - just get shut of it completly

[m1tch]

I might remove my ABS as well, all it seems to do is randomly fix itself - like this morning for about 10 minutes and then fail, it also removes quite a bit of skin from my knuckles when I am trying to get to my coolant leak lol I think I might remove the ABS pump to make room for...something else that is shiny maybe?

[Adam fc]

Oil catch can?? I removed my abs pump today along with all the lines along the firewall ready to have some new lines made up.

I assume you just buy a t piece and join the front brakes together and then to the master cyclinder, then run a new line from the master cylinder to the rear brakes??
please correct me if im wrong?

[Furb]

when i removed ABS i just bought the FC non-ABS brakelines at our local dealer.
but you need to T the front brakes together to work with the stock ABS master cylinder.

[Adam fc]

yeah i see there is only two ports in the master cylinder on mine so ill get a local garage/mate to make some lines up and see what it feels like when its done.

With regards to mot will i have to remove the ecu,idiot lights, and all sensors to get through??
