changing rear axle - gazthegnome - 02-04-2015
how easy it it to change my rear rear axle with drum brakes to and axle with discs and what if anything else needs to change when i do it
RE: changing rear axle - Toms306 - 02-04-2015
Very easy in theory... But seized bolts and brake unions will probably make it difficult! Dropping the beam is only 6 nuts accessed from the boot, but disconnecting the brakes, backbox, spare wheel for access is what causes problems.
The only thing you NEED to change is the handbrake cables, they are different between drum and disc brakes.

cheers mate

Brake lines are different too I think.
RE: changing rear axle - Stef205 - 02-04-2015
brake lines are different from phase 1/2 to phase 3 as they didnt use a bias valve but is easily converted.

Is that the case between gti6 beams of different phases as well?
RE: changing rear axle - Stef205 - 03-04-2015
yes it is i believe, but its only the rear mounting arm braces that are different its all interchangeable so its no biggy

Ok great thanks.

The brake hose brackets are permanently fitted onto the ph3 beams and aren't compatible with the brake bias valve, but you can just swap the whole beam bracket for your old one. Or do what i did and wait until you're under the car before realising and take an angle grinder to the bracket in anger.

Ok thanks.
Got a rebuilt beam to go on but don't know which phase it is from.

Make sure you've a pair of mole grips. The unions on the brake pipes can be a complete twat. One of mine came off fine, the other was properly seized.
RE: changing rear axle - RetroPug - 05-04-2015
I've got a pair. So far I've removed calipers but left the brake lines all attached. My plan is to swap the whole beam back on, loosely bolt the brakes on and give them a bleed and if I do that successfully and don't shear the nipples I'll put them back on properly.
The brakes seemed like they were binding though so should probably look at that too. Probably the piston needs a greasing I'd imagine.

If the piston is pitted or scored it's time for a new one, more likely it's sticky sliders or dirty carriers though.
