Just re did my front calipers with new seals from Repco. New PBR Brake master cylinder also.
Just went down to Supercheap and got front n Rear pads that are on sale today for like $53 per front n rear.

New master cylinder....Noice....

Will be interesting to hear your feedback on the brake pads you bought, seeing they were the price they were.....Personally I have no issue with the price you paid nor the brand....

Hopefully the rest of the installation goes smoothly...One headache is enough with the system....

Yeah when I bought my ute MC I found sedans ones still available. For some reason though no one I called could get me a ute MC. Then VSL managed scored the last one in the country.

Why on earth would you use a G clamp to push back pistons in a caliper that is off the vehicle and should have no resistance? If it won't push in with your thumb then there is a problem.

part of the answer is below

once you've done that carefully and squarely push the piston into the bore ensuring the seal doesn't pop out of that groove in the bore

Using the old pad and a g clamp without having to buy extra tool sheet helps to squarely put the rest of the piston in, yes there is some resistance with new seals which stop leaks when under pressure and the seal expands further.

Some info, yes there is/was a specific red organic lubricant that was used instead of brake fluid for all hydraulic seals/piston and boots for brake/booster components/installation .
I can't remember the brand as it was many moons ago when I used to help out in the hydraulic brake section doing recon units.

"Nah mate it doesn't exist........... Oh wait yea nah that's brake fluid I tell ya" "even though I said it doesn't exist I now know it's exact chemistry"

There's tools then there's tools.

For the last hour ive been trying to install a dust seal on the piston to go into the calliper with a Protex kit and im about to give up and ask a mechanic to install it, is there a easy sure way to do this? Im not using red rubber grease just some brake fluid I was able to get it on once but I forgot to use brake fluid and I couldnt push the piston in even when using a piston pushing tool I stopped because it would of tore apart the seal. How do mechanics do this do they have special tools? Since I dont have any red rubber grease is it ok to use vaseline.

There is a trick to it,
No special tools, and patience is required.
