Does anyone know any brake specialists in Sydney who are not going to bend me over the desk when they give me the bill?

Why do you need a specialist to work on your brakes?
Any qualified and competent mechanic should be able to fix any braking problems. Even todays ABS is no rocket science....

But if you insist, Burt Bros at Fairfield would be my choice.

Thanks for the recommendations guys i will make some calls.

As a matter of fact I am a qualified and licenced motor mechanic but this problem has me stumped, as well as other mechanics I have discussed it with. Of course I have my suspicions as to what it could possibly be but it requires more parts which I dont have the money to just keep throwing at it with no results. If I can talk to a brake specialist who seems confident in what the problem could be I would be happy to pay him to rectify it.

Car pulls quite harsh to the right under heavy braking. Have replaced all front suspension bushes, shock absorbers, master cyl, front pads and calipers overhauled but problem is still there

rubber lines all  good ?

Just as an aside
has your car always done this ????
it is a converted car ,maybe it is bump steer introduced when the car was converted

I would guess that the better you make the brakes (as in reconditioning  ) the more pronounced  the pull to the right becomes

I have had the car for about 5 years and it has always had it but it started out very minor and has progressively gotten worse over time. I thought the line may be blocked as well but both sides bleed just fine ie: minimal pedal pressure required and fluid flows freely.

I would be looking over the suspension again very carefully.
You may have replaced all your bushes but one of your control arms may have a small crack or slight bend in it that would cause it to flex or bend under heavy braking resulting severe bumsteer condition.
Other issue could be your flexible brake line could have collapsed which you will never see from the outside, so replace them with braided ones see how you go.


If it all fails bring it to my work and i will go over it and give my advice free of charge.

Matt, I'd even go one step further than Chris and say have a look at possible cracking in the chassis.  

I speak from personal experience.

The combination of RHD conversion and old age can do some funny things.

be interesting to see what happens when you put the car in reverse and hit the brakes hard ........if it pulls the opposite way then have a really good look at the lower control arms/chassis

Well guys the problem has been sorted once and for all. I was always certain it was not a brake problem but after speaking with many suspension specialists I was told no way would it be a suspension problem. It was all caused by a bent rear sway bar link. When it was fitted to the car it did not stand out as being bent but what was happening was as you applied the brakes the rear of the car lifts and as the sway bar links were effectively two different lengths it would pull the diff at an angle and cause the car to rear steer.

Maybe there was a reason that John Delorean never believed in rear sway bars.:smile:
