Evening,
As I'm still eagerly awaiting the chance to either collect the nova or have it delivered I decided i might as well get on with a few bits in the mean time.
Here goes then first off a classic brake upgrade to the Astra GTE 2lt 16v ATE calipers and 256mm vented disks. Nothing too exciting but worth it never the less.
I had previously started cleaning these up for another project then put them to one side and forgot about them so they weren't too bad to start with as you can see below:
Like a T1T i forgot to oil the bore of one of them when they went in to storage so i need to sort that out.
Carriers are ok just a bit of surface rust
Sliders and springs are ok still
Finding one of the pistons had a groove in it was the reason i shelved them the last time - Ive sourced a new on to replace this
Other pistons ok just crispy on the end
Caliper to hub bolts are a little rusty they will come up nicely though.
To start i degreased and hot washed all the bits
Then protected the sensitive areas ready for blasting
In the blast cabinet they go
Bolts have come out clean
They still look ruff though
Caliper bodies and carriers have come up nicely
The one remaining piston gets the blast treatment
then a coat of acid etch primer
The carriers get an etching too
Leaving them to dry i turned my attention back to the Caliper to hub bolts
In the lathe they go for a further tidy up
All four complete after having cleaned up the heads and the threads
Gave them a quick squirt of spray grease and bagged them along with the other bits for later
Next ups the caliper bodies
The worst looking rust but not dead
Weapon of choice one times fiber wheel
To go in here
Knowing there wouldn't be the reach on the spindle a home made extension was needed - cheers Nige
clearance granted
Next issue - the profile of the bottom of the caliper bore seen below
i needed to machine the black resin out of the bottom of the fiber wheel to clear this
Better
Fiber wheel in the mill at a nice high speed on the extension
much better
Both whizzed
After degreaseing i protected the sensitive surfaces again then applied etch primer
They have come out well
Ready for a top coat - probably a nice gold again to compliment the brown?
