Replaced front hub bearing a few weeks before Christmas.
Checked and adjusted front and rear after that.

This problem was happening before any adjustments and still gives the same symptoms after the adjustments.
As said earlier in the thread (I think  )

I started noticing it after the rear springs was changed for the MOT last September.
I knew I had work to do on the brakes so "lived with it" until I worked my way threw the list.
The list includes .................
New front discs and pads
Replaced 1 rear disc and both pairs of pads. (the other rear disc was spotless)
Adjusted the handbrake.
Replaced 2 front tyres.

Did you do any rear caliper work? Guessing offside rear disc was the clean one...

Handbrake cable routing following the spring change? If the cable is being pulled by suspension travel as the weight shifts forward under heavyish braking, that could brake one rear wheel, increasing the braking affect on one side causing the pull. Wouldn't show up on an MoT as there's no weight transfer during the brake test. Sticky rear caliper would have the same effect, but should be picked up by the tester unless both sides are underachieving equally 

Only other candidates are front arm ball joints, shocks or front arm rear bush

I'm going to take it back to the tyre place, first thing in morning so they can get it up in the air and have a pull around with various bits again.

Since these symptoms only happen AFTER a few pushes of the brakes / bouncing over speed bumps, personally I can only think of 2 things

1/.  Knackered shocker (dumping pressure after a few bounces)
2/. Air bubble in the brake fluid

Then again, I may just be talking shite

Rear nearside disc was trashed when a brake pad broke up and the rivets scored opps out of the disc before I could get the locking wheel nuts chiselled off. (that was 2 years ago. I just replaced the pads because I was skint at the time)
Handbrake was just adjusted up on the adjusters visible with the wheel off because it was borderline for the MOT. The cable was left alone.

I know the front wishbone bush can be changed with out removing the arm.
Can the rear one be done without removing the arm ?

Rear one no ball joint can be, but is a shit to do in situ and still ruins the geometry...

I would budget/start collecting bits for a front end rebuild then, as it sounds like the brakes aren't the issue...

What is the best way to check the rear wishbone bushes ?

[05omegav6]

Physically... Pry bar in behind from the trailing edge of the arm and try to pop the arm out of the subframe... significant play means they're toast.

Visually... look for splits in the rubber... should be obvious on top with the car jacked.

 

[tigers_gonads]

Rear bush (into the subframe) near side well and truly knackered
Some play in the off side too so it looks like i'm going to be replacing both pairs of wishbones / track arms when it warms up a little 

Thanks to Al (and Chris if your lurking) and any others for listening to my whingeing  helping me out on this 

OOF at its best imo 

If I can hold out until I find the dosh, i'll stick B4's on the front end too and maybe poly the front bushes 

[05omegav6]

This should help with the cash side of things...

My money is on dodgy front wishbone bushes. Four years ago I put Jonny's Omega through its MOT, found it twitchy on braking, didn't like it. Changed discs and pads, just the same. In desperation I had wife drive car over the pit and brake with me in the pit. Then it was obvious - front bushes. Yet the MOT man had found nothing wrong.

Not entirely the fault of the tester as the car is tested static, so absolutely no dynamic load... roller test demonstrates nothing beyond brake balance and efficiency

The modern one man testing system with shaker plates ought to have found that

Theres a truck load of compliance in the front bushes anyway even when there not worn. Thats why the polys go in.

I had the same problem. Seem to come from nowhere. Within a thousand miles or two, the track rod end seemed to have as much play as your average taxi.

These newbies can be demanding..
