My Jazz is CVT but my Yaris is manual with an hydraulic clutch. I changed front discs, brake fluid, and bled the clutch when I got the car. It helped the clutch feel and weight (pedal effort/smoothness) significantly.
I despair of some mechanics these days. If you change the brake fluid in a car which uses a common brake/clutch fluid reservoir, it takes literally 2mins to bleed the clutch line and something you'd do as routine so that the new reservoir fluid can't get contaminated with old dirty fluid from the clutch system.
In an ideal world you bleed the system through until nice fresh fluid comes out, then get someone to hold the clutch pedal down and then gently release the bleed nipple and let the slave cylinder leak down which helps purge old fluid out of it. Do that a couple of times and you're fairly sure new fluid will have got into the slave cylinder which is often slightly beyond the bleed nipple, right at the end of the line.
