Title: heavy pull under breaking
Post by: Aundie on 14 July 2012, 21:00:45
Developed a nasty pull from nearside front wheel when cornering or breaking always pulls one way then the other moments later I'm guessing wishbone bush. Thoughts appricated.

It's quite possible that you need new brake discs, mine developed this, new discs & pads sorted it.
This is a possible solution mind ;)

There s a very distinct difference between a pull due to brake imbalance, and a pull due to failed wishbone bushes.

But for the life of me I can't explane it on a written page. Both are very distinct possibilitys. I suppose brake imbalance is more subtle and is fealt through the stearing far less, and you just have to stear the car back on line.

Wishbone bush pull has a very distinct affect on the steering, as effectively the Track rod length is not able to match the hub centre to centre distance which is moving due to failed bushes. Therefor the feed back through the steering can be quite horrific, with steering turning opposite to the cars direction.

Suspect wishbone bush failure may well be likely. But both are possible as said.

This is a scary violent pull throws the front end visibly real nasty on roundabouts.

Then springs back with the same effect when you counter steer.

If the pull is consistent .. ie .. same direction, same force, every time .. it is far more likely to be the brakes than the suspension, as the suspension is remaining "fixed" and just the brakes are involved.

If the pull is inconsistent ..  ie.. it is different most times, and changes whilst occuring ... then it is likely to be suspension ... as any movement of the suspension will have a different effect, and the moving suspension causes a changing (moving) effect.

The suspension will try to move a lot under braking .. it is not supposed to move in several areas ..but if worn those bits will move ... unpredictably ... :(

Just my random thoughts .. nowt else .. :)

It's definitely coming from the nearside front and always throws to the right then back to centre you'd assume if nearside brake was biting you be thrown left my opinion only. Also tc and abs lights come on now and again.

A rolling road will prove/disprove a brake imbalance.

Bushes.

Although, thinking further, a full check would be wise. Steering idler, track rods, steering knuckle etc. anything that could allow the wheel position to move. But my money's on bushes, primarily the rearward vertical wishbone bush.

Tc light will flash on because the system is trying to straighten the car up :y
