Need some advise of you guys? Went to Change my pads and discs today, following a very good guide on here. Now I got as far as pushing back the pistons back on the front and they wouldn't budge. Tbf I don't have the proper tool I tried bodging it with a g/clamp. But still the piston was so tight it only moved a few MM. Before the glamp broke! Would you recommend buying the proper tool? I thought they would go back relatively easy but the must be slightly siezed. Oh and I took the cap of the brake fluid tank as well. Cheers.
