REAR BRAKE CALIPER PREP BEFORE SANDBLASTING
Before starting the sandblasting process on the rear brake caliper bodies, I needed to properly mask and protect a few critical areas. In particular, the hydraulic piston bores and the internal brake fluid channels or ports must be shielded from blasting media to avoid damage.

My approach was straightforward. I used masking tape to seal off the two fluid channels that allow brake fluid to pass between each half of the caliper. For the hydraulic piston bores, I inserted a dense foam material to fully block off the openings and prevent any abrasive media from contacting the internal aluminum surfaces.

After about an hour of work, all the necessary areas were sealed and protected. The foam inserts worked particularly well for the piston bores, creating a snug barrier. For the fluid ports, I used a simple but effective technique—lightly tapping around the edges with a hammer—to cut perfectly shaped circles out of masking tape for a precise fit.

That’s as far as I got for the month of July. Progress may have been limited, but it’s a solid step forward. The next stage will be to begin sandblasting the calipers, which I’m aiming to tackle soon.

Well I have finally started to take my dash out.
I have given up outside for today, come in to build my gauge cluster.
Following issues so far:
Cant get the bloody hazard switch connector off
Fog light switch has been bodge soldered by prev so im gonna have to cut the wires.
Cant get the stpuid connector off the internal temp sensor
Cant feel a screw head in the rear of the steering wheel to get the cover off, to get the wheel off.
Can anyone help with these?
Can of worms lol!
