How to make the disc brake spreader?

How hard do you think it is to make a Disc brake spreader and how would i go about it?

Do you have dimensions etc that i could work from?

Cheers

Welcome to the forum!

Are you referring to a disc brake spreader for rear disc brakes calipers with integrated parking brake, the kind that need to be rotated as they are compressed? If so, do you have access to the steel stock and machinist tools (metal stamp, mill, lathe)? If not, you might save money in the long run to order one.

Or, if it's just something you need for personal use when doing brakes, why not borrow the kit from your local chain auto parts store? As long as you return the tool within 90 days typically, it won't cost you anything.

To spread some rear disc brakes, you can use two large adjustable pliers, clamping at each end of the pad against the caliper.

For many front disc brakes, you can squish the pistons back in with a simple large c-clamp and a piece of wood, or a small to medium vise (and woodblock).

Make sure you take top off brake cylinder and remove brake fluid first (use a clean syringe or handpump).

Some rear pistons have to be 'screwed' in with a special tool, that is a combination 'c-clamp' with a fancy key end and an extra 'nut' bracket. These tools are about $40 and are easier to buy than make.
