Hey guys. Just attempting to get some new RDA pads and disks on for much needed braking power!
Now i am stuck trying to get the pads to fit in the caliper and get the whole lot back onto the disk and mounts. The cylinder things inside the caliper wont allow enough room for me to get the pads on and slip the caliper over the disk.
Ive tried searching for a pad change guide but all of the similar posts aren't helping. Have i something up bad?

G-Clamp.
Use one to push the piston (cylinder thing) back into the caliper.
One side of the G on the back of the caliper, one one the piston. You may need to put something in between the clamp piston and the caliper piston as it'll just slip into the piston itself. You can use a strong piece of metal, or even the pad itself.
Be careful not to crush any hoses or fittings on the rear of the housing.

I just use a large pair of pollygrips set to the correct width, with a couple of vinyl strips over the jaws so they don't scar the metal - G clamp would do the job too but might be a bit harder to fit in. You can actually get a special tool for this job, but it's a bit of a waste of money really, unless you are doing the job all the time, as it's not of any use for anything else.
Make sure you remove the cap from your brake fluid reservoir and remove any excess fluid with a syringe.
Last tip, smear a bit of copper grease onto the pads and backing plates - helps with heat transmission and reduces brake squeal.

Ensure you drain/suck out some fluid from the brake fluid reservoir before you start to push the pistons back, otherwise it will push past the seal under the cap and leak all over your paint!!!!

isn't the brake squeal there to let you know the pads are worn...
Different squeal, there's a metal bracket attached to the pad that will scrapes the disc when the pads are worn down far enough, causing a squeal to tell you it is time to change the pads.
Putting copper grease on the back of the pad stops the squealing noise from the pad squirming around on the piston as it grips the disc (there is always a bit of float in the pad so it doesn't bind up). Some pads/calipers have metal shims which do the same job

Yes, I'm talking about squeal from new pads, not worn pads The Soarer has a set of two anti-squeal plates on each pad, but in practice I've found that sometimes isn't enough to stop some pads from making irritating noises, so I still put copper grease on the back of the pad before putting the plates on over the top.
