rear backplate catching, grinding,

[pkrboo]

Finally got my Doka back on the road, passed MOT first time with no advisories (MOT place is 150 yards form where the doka was), drove it a couple of miles and it started making a horrible noise from the rear brakes, rear left, NS to be precise. The right hand side is fine in all of this

The noise only seems to happen when steering left, steering right makes the noise go away.

rear brakes had new backplates, new shoes, new cylinder and good used drums. found the back plate was catching so ordered another, and also fitted new wheel bearings.

after fitting the new backplate, and a new drum, (although the new drum instanltly locked up on the backplate when the wheel was tigtened, due to tolerances i believe) the noise still happens.

so next time it was expensive VW classic backpalte time and whilst it now accepts THE new drum and spins beautifully when jacked uop whe i go for a drive it still catches/rubs.

not sure where to go next.

Offisde is fine. Caste nut is torqued up to spec of 500 Nm

New parts fitted so far are:

VW classic backplate, (and previusoly 2 classicline backplates)
wheel cylinder
shoes and springs
handbrake cable
drum

New FAG wheel bearing kit in a good used carrier (inner bearing fitted using Loctite 638)

second hand parts

wheel bearing housing
drive falnge
stub axle

Not sure where to go next, feels like its bearing related still with the change when I steer left and right


Anybody else had this sort of issue?

Id paint around the plate, fit the drum etc, go for a drive and come back. Remove the drum and see where the paints rubbed off. Then probably pry the plate away from the drum a bit.

I had the same symptoms last summer after fitting new genuine VW backplates whilst doing rear wheel bearings etc.

It was fine on the drive on jacks, but made a horrible noise going round roundabouts and corners once warmed up (as we got further away from home of course)!

I think that the new back plates must have been slightly prouder than the originals, but some hefty nudging of the back plate away from the drums with a large screw driver helped things along. I had it on both sides, but worse on the left.

Stesaw's idea would prove that's the issue.
