Hope you guys can shed a bit of light on this...

A while ago my right front calliper sized up completely whilst offroading, fixed it next to the road and all good, chk and clean again at home to ensure all is still good..

But the other day it had a different idea, now when braking hard, ie in an emergency, I just get a solid pulsating/vibrating paddle, as if the ABS kicks in, but the Jeep is not slowing down at all...

As the calliper is playing up, I'm replacing both of them, brake lines  got 90k on and seen better days, so replacing them as well, and while at it, replacing the brake fluid

Really hoping this will sort my problem, but anyone got thoughts on this??

Do you have ABS?  If you do then make sure the wheel speed sensors are clean.

I do have ABS..  Will give them a wipe to ensure they nice and clean

It sounds like the ABS is doing exactly what it's supposed to do.

Like not stopping the Jeep in this case

If you can scan it do so, if not, replace ALL the wheel sensors.

Help me out here, how do I scan it ??

[Cockney Boy]

eBay fault scanner, you can pick one up for about £15 coins

[Arno]

Ah, got it

But will I see fault codes on the dash as well ?? I dont see any..

[Nosebolt]

scanners are usually stand alone units either with built in display or like the one I just got a bluetooth sender that displays realtime data on my phone

[Mike Pavelin]

An Ebay scanner ain't likely to be able to get into the ABS system. If there was something wrong with the ABS that a scanner could see a code for, the warning light would be on and it would shut down. One exception being if there is a slight problem with a tone ring or sensor which still gives a plausible signal in which case the ABS can kick in prematurely. This wouldn't log a code anyway.

[Arno]

Very true,

I have no error codes or warning lights on the dash, so will clean the ring and sensor, look for any obvious damage on them.

Hopefully all this will sort the problem

When the ABS light came on on my dad's Rover we used to disconnect and test the resistance of the sensors with a multimeter. Which ever one registered open circuit was the bad one. I presume Jeep sensors could be tested in a similar fashion.

[Arno]

I guess so, but in my case I don't have an ABS warning lights thats on
