Some advice please

My 1994 300tdi 90 needs new pads, discs, callipers, shock and springs.

Was wondering as it came with indeterminate history a year ago what else I should do whilst I and doing the above. E.g. if view got that much off each corner what else mights as well do at same time

Thanks

Turret rings, maybe turrets if they look at all suspect. Check brake pipes and maybe invest in a flaring tool.
Jobs like this always grow for me!
The caliper pipe will break, can't get the other end off the flexy hose so need new hose, caliper bolts get mullered, shock bottom nut won't come off, Access is bad, buy a sabre saw(as I call them) to cut it off etc etc.
I've got all this stuff so no biggy for me just forewarning you what MAY occur..

Thanks - yeah added turrets and bolts etc.... was thinkingflexi pipes and calliper pies..... is it worth doing anything to bearings and hubs whilst everything is off

The hub has to come off to replace the discs so seals will be disturbed, if bearings are good, wash in petrol and regrease, seals need to come out to remove the outer bearing race.
Belt and braces is new bearings and seals, quality parts there only.
New drive member gaskets needed too and lock washers for the hub nuts.
I double up on seal, gasket, bearing orders so I always have spares and don't get caught out on a Sunday or something.

If you haven't already got some you'll need some threadlock for reassembly.

Unless the existing braking is working really well and the flexis look recent I'd be changing the flexi lines too. While you're doing that there's a fair chance that the existing solid lines and joints will be damaged, so do the lot. If the braking is a bit suspect there's a good chance that the existing 26 year old calipers are partially siezed. They can be rebuilt fairly cheaply, if you have the skills/tools, otherwise it might be wise to budget for replacements. Personally I'd also rebuild the master cylinder with a new seal set. If there's any sign of it leaking when splitting it from the servo I might replace it instead.

If you are fitting new calipers I would replace the caliper pistons with stainless versions before fitting that way they will last longer. Other than that everything already mentioned by others.

Some advice please
