Working on an 85 HE, for those of you that helped last time you will be happy to know the cooling system is now working perfectly with temp nailed on the bottom of the N. I have pulled the front wheels to inspect and overhaul the brakes and they look like something of the titanic - utterly welded together with corrosion. After mega frustration and a good air hammer session I have managed to separate the callipers & pads from the disc and hub (have already accepted that the discs are a lost cause) and have left the hub assemblies to soak in penetrating oil overnight.






My question is, is it really necessary to access all (5?) hub bolts through the dust cover as per Haynes or is it easier to remove the covers and then do it? It feels like the sometimes you are required to have the dexterity of Dr. Octopus to accomplish what would be a 20min job on a modern vehicle. As always advice would be appreciated. No doubt I will be back again for the rears, I hear they are the mother of all swine to replace

 

I'm a bit lost with repsect to 'dust cover' and 'covers'. What are you referring to, exactly?


I haven't looked at a Haynes in years but I suspect it does the same as the Jaguar manual in described a method of removing the brake discs from the front hubs *without* removing the front hub.

Is this what you're referring to?

Frankly, I never saw much point in this method. I find it awkward getting a socket onto the bolt heads.

I simply remove the caliper (which I think you've already done) then remove the hub and disc as an assembly. Now the entire shebang can be plopped onto your workbench and you'll have easy access to the bolts that hold the disc onto the hub.

Naturally this is the prime to clean and re-pack the front wheel bearings. If yours is like most I can all but promise it's overdue!



Or......am I misunderstanding what you're asking?

Cheers

I think the OP means these Doug 10, 11, 12:

Cut off the shields and throw them away! Then undo the disc bolts normally! While you are in there, if funds run to it, renew the front wheel bearings and check the stub axles for scoring. If they are, replace them. It might be better to fit new calipers, if funds allow, but certainly a rebuild of the rubbers, seal etc.

Did you save the shims under the bottom steering arm bolt, between it and the caliper? As you say, the fronts are just the warm up act, the rears are the real thing - nothing that cannot be done though!

Thanks for the responses, Doug / Greg. Between you I have a better idea of how to proceed. The rears I am saving for an ultra-enthusiastic weekend which will also involve beer.

 

And Greg those are exactly the parts I mean, on an Audi they would be referred to as dust covers - I really need to work on my Jag terminology :S

 

hub bolts?? As in hub to the rotor? The rotor just comes off. take the hub off the rotor with an impact on a tabletop. I must not be understanding the question....
