It's not the first time I've posted on this, so just wondering what your thoughts are about this ongoing problem.

 

The chaps at Zedworld fitted the driftworks total eliminator bar to get rid of the HICAS and I couldn't be happier with that.

 

BUT the car just won't stay straight like it should. Let me explain -

 

1. High speed, i.e. fast, touch the brakes and it will snake all over the place, a bit spooky if I'm honest

 

2. A bit of judder under medium braking

 

3. At very low speed, it is sometimes pulling left and sometimes right, not a lot, but noticeably, the steering wheels turns by itself i.e. a quarter turn one way or the other

 

Now, all wheels are high speed balanced, tracking done, tyres all good. Rear brakes and discs good. Front discs quite new as are pads. It's an import with 8.5J's all round instead of 7.5Js.

 

I doubt that it is disc warping or uneven pad wear or both and I'm thinking it could be a caliper issue or a steering rack problem.

 

Ring any bells? Anyone know how to tell if the steering rack is u/s or if a caliper is causing problems?

 

Cheers, Alex

how long ago was the brakes tested or moted tested? must be something wrong there

It's only just passed the MOT, the only advisory was a passenger side upper link that Zedworld already replaced for me. Other than that, everything was given the ticketeeboo.

I'd say your alignment is out of whack, have it redone at a different place

The thing is, if I stomp on the brakes and at any speed up to about 70, it brakes pretty much in a straight line. The steering is very light and it has a bit of play. The alignment report suggests it's not out of alignment too.

 

At high speed, it sits straight. At v.low i.e. 3mph it pulls one way or the other. If the alignment was out, wouldn't it pull one way consistently as opposed to varying?

It could be a caster angle problem, as jaffa say's get the alighment checked.

Just looked and it was last aligned in Sep09 when adjustable tension rods were fitted, so perhaps you're right and a sensible first step. I'll get it done.

 

Anyone recommend a reliable outfit in Berkshire or near by?

 

Thanks for that guys, Alex

Btw, I think the last chap said something about the steering wheel not being on straight, which sounded like a dose of b.s. to me. Here's the last wheel alignment report.

 

Alex

sounds like failing tension rods but you have adjustables, i would check there first though

Just to paint a complete picture.

 

Do you have standard brakes?

yep, bog standard

Have you checked for free play in the wheels when jacked up?

 

try pushing outwards on the inside of the frontwheels, when in the air, to see if there is any play in the front wheels/steering etc

Just a possibility, I know you said you have a hicas eliminator bar but the rear track rod ends should still be in place, the ball joints may be worn causing your rear wheels to turn a few degrees back and forth.

 

Jack up the rear from the diff and check your rear wheels for play left and right, it will be apparent if the balljoints have worn.

Just been diagnosed with chronic upper link disease. Is it worth replacing just the bushes, go adjustable or fit good seconds?

 

Had the front brakes sorted and cured one set of problems, now these links ... anyone got a top set for sale?

 

Thanks, Alex

Stick a wanted note up in the trading section if you can't see any advertised.

 

Failing that, get the car back to Zedworld and/or ask Jeff/Jamie to source you some decent parts from a breaker.

have you spoken to jeff?

I would say you have a caliper problem. one of them could be sticking by the sounds of it.

 

It sounds like one is slightly binding so when you press the brake it will pull you over to one side because it is already technically allready on, then the other grabs and straightes it up.

 

Also with the friction it will heat up and exaggerate any slight warpage on the disc you have,

 

I have the same problem on the BM at the min, and trying to get the caliper boly off i have snaped 2 spannes :(
