Nativa brakes : Ive just replaced front fibers on nativa 98 but did not replace ¨winder brake ¨ = rear brakes. Now the mechanic tells me is normal to pump brakes because rear brakes change the entire system condition ( end running = final de carrera ). Is it true?
what I don't understand is why the car used to stop on brake touch with bad fibers and regular rear brakes now with new fibers I need to pump brakes

Replacing the front brakes has nothing to do with not replacing the rear, unless the rear are worn as well.

Something is wrong if you need to pump the brakes to get it to work.

Is the pedal lowand pumping makes it higher?

Are the front rotors in good condition?
Get a second opinion, the first does not seem to know anything about brakes.

Recheck the work done. Ensure the caliper slider bolts are not seized.

With engine running, pump the brakes and hold the pedal, if it sinks, you have a failed master cylinder.

After replacement of the front brake, the calipers would be pushed back to its maximum and the first few strokes would result in very low or no pedal pressure at all. If during this few strokes you had fully depressed the brake pedal, it is highly likely that the master cylinder seals had failed.
