It was all going so well.... I was trying to push the pistons out of the front brake calipers by removing one of the brake pads & applying pressure to the brake pedal but they didn't want to budge. Finally the pedal started to move which got my hopes up but when I checked, the pistons were still in the same position

When I looked towards the rear of the Delta there was a pool of brake fluid, one of the pipes had split

. Unfortunately it had been leaking for a little while before it finally split as the paint had lifted on the bottom half of the rear crossmember

. So today I removed the rear crossmember & I'll be looking at getting it powder coated also I've ordered some new front brake calipers as the old ones are seized solid!
