technical question - unwanted steering - bob
hello

i have a problem with my car that when i brake the car trys to steer to the left, and it is a bit of a problem, especially on the motorway as it can catch you off guard.

the car doesn't have abs or any fancy brake equipment, just a diagonally split system with discs and drums.

so far in my efforts to find the cause i've:

bled the brakes (in case there was air in one of the circuits)
checked the drums to make sure the handbrake cable wasn't affecting the self adjusting mechanism.
changed the tyres right to left, and vice versa - to see if uneven wear was a problem.

which now leaves me wondering what to do next....

i can't see anything wrong with the calipers at the front, and both seem to be wearing equally.

my worry now is that the front wishbone bushes are worn, which means that under braking the steering geometry is altered, and thus the problem....

any suggestions are very welcome, as i'm stuck for an answer, and i don't want to hand the car over to the dealer just yet.

thanks

I would suggest a complete geometry check .Have you changed the fluid recently .I had the same problem on my sons car and chanching the fluid cured it

a long time ago, my car went into the garage for all new brakes, but the idiot who did the work, forgot to put new brake pads on the drivers side, so the car had three new brakes, and the worn old one, so it was going to the right when i braked.

oh you are joking, I used to live just outside Raleigh.
Re: technical question - unwanted steering - chris watson
the first house was in wake forest, but that was miles from anywhere, so we moved to raleigh, but that was in 1984. do you remember winn dixie, (i think thats the spelling)

You mean the shopping place ?
Re: technical question - unwanted steering - chris watson
yes i do mean the shopping place, i think the street was called silverleaf place, i am not sure about the "place" but i am sure it was silverleaf.
Re: technical question - unwanted steering - chris watson
by the way silverleaf was not the place that had winn dixie, silverleaf was the street that i used to live on.

Guys,

Really spooky. Do you know the Harley dealers in Raleigh? Come in from Chapel Hill, down Wade ave and a right into South Saunders St. (might be one way now so perhaps you can't turn right).

we used to live near a road called "falls of neuse" but that was in 1982.
Re: Coincidences. - Mark (Brazil)
I don't know if its still there.

Mate of mine, Joel, has got a Harley, he's a rabbit breeder, lives on Spring Valley Road (864-578-6466 if you want a rabbit) and is always complaining that he has to drive right across town now for a service.
Get it checked out NOW! - David Lacey
As this is a safety related issue - please take your car to your nearest dealer/MOT station and ask for a brake efficiency test. This will highlight the probelm if it is indeed a braking system fault.
This is a potentially lethal fault, please get it sorted ASAP.

P.S. What car is it that you have Bob?
Re: Get it checked out NOW! - bob
it's a '97 fiesta. and perhaps i've over stated the severity of the brake pull. it's only noticable when you brake hard, and i doubt some people would even notice it unless they really had to stop in an emergency.

it had an mot quite recently, so hence the wonder about the bushes having worn, but yet weren't picked up upon.

Re: Get it checked out NOW! - chris watson
the 1997 model fiesta had a recall, something about the brakes. i would make sure with the dealer that the problem was rectified. also for the details of the recall, go to parkers.co.uk and go into the owning catagory.
