Bleed or replace pads first??

[Speed Buggy]

Good Morning gents and ladies- I am going to bleed my brakes and replace the pads. Should I replace the pads first, and then bleed the brakes, or vice versa Thanks

Cheers, Mike

You must pry open the caliper pistons to install the new, thicker pads. Some say that this could cause an overflow at the resevoir. Then, you must seat the pads against the rotors. I would bleed then, or maybe just check the fluid level, go out and break in the pads and bleed after that.

If you use the power (pressure) bleeder, don't forget to clamp off the overflow hose.

You would want to bleed last. If you are able to push the pistons back far enough to get the new pads in you might not need to bleed. The new pads are obviously thicker so your pedal might be a bit firmer.

Thank you very much.

You are going to turkey baster the fluid out of the resevoir prior to changing pads, so that the new thicker pads doesn't overflow the resevoir when you spread the pads to put the new ones on.

Change pads, but do not seat them yet.

Hook up your power bleeder after filling the resevoir with new fluid. Seat them, bleed them.

Done.
