Garage / Re: Removing Stuck Brake Caliper Pistons
« Last post by 4129R on Today at 03:06:08 AM »I have found a very easy way of getting stuck pistons out of the calipers.
Remove the caliper and both pads.
Make an extension to the brake pipe and connect the caliper on the ground.
Use the foot brake pedal to force one piston out, the second will not come all the way out before the first breaks the fluid seal.
Get an old brake pad (I had one where the lining had become detached through age), make up two ally plate spacers, and fit one new piston in the half of the calliper where the old one came out. Fit the old pad against the new piston, fit the spacers to hold the new piston fully back in the calliper, and use the foot brake pedal to force the second piston out of the calliper.
The overhaul kit was £40 including next day postage (arrived at 4pm the next day) from eBay. Triumph Spitfire Mk 3 and 4. It included the square section O ring for between the two calliper halves.
You need lots of brake fluid to press all 4 pistons out, so make sure you have plenty available before you start.
