Advice for changing break pads (lemm.ee)

So it's come the time to break the pads on my car which is a Kia Rio. I've looked up a few things and the job seems doable by myself which saves a lot of money.

The only thing that I can't seem to find a concrete answer is if they actually need to be bled once the new pads are installed?

Thank you

You only will need to bleed, if you open the system, e.g. to replace the cylinder.
When you only change the brake pads, you are pushing the pistons back and thus, should keep an eye on the reservoir tank near the ~~motor~~ engine so that the brake liquid doesn't spill over.
However, every one or two years, you should also exchange the brake liquid. The liquid it is hygroscopic to avoid corosion in the system, but the water bounded by the liquid can create vapor bubbles if the liquid gets hot yielding to fading effectiveness of braking.

A brake is a device to stop or slow a vehicle, and braking is what you do when you apply the brakes. Brake pads are what OP is talking about replacing.

Breaking something is separating it into pieces or interrupting a sequence of events, like taking a break from work.

Thanks. I must have had a blackout and blindly followed OPs spelling.
