Brake pedal travel? (1 Viewer)

[Bessy765]

Hi all we have a 2019 Burstner A Class plated at 4500kg currently running at around 4300kg. Have noticed that when braking all. Works but it seems a bit more pressure is needed than previously, if I give the pedal a light but quick pump the result is firmer braking with a lot less pressure. We have covered just under 20,000 miles not a heavy brake user prefer to slow down earlier, we have owned from new, pads are fine no weeping around callipers or rear of master cylinder or loss of fluid.

Sounds like fluid absorbed some water. But age doesn't really tally up?

Brake fluid should be changed every 2/3 years.

An easy check of the servo operation: Engine off, pump brake pedal several times, press and hold pedal down, start engine, brake pedal should dip almost immediately. If it does not, then look at the vacuum system.

What does the brake pedal feel like when the engine is off. If the pedal is hard with the engine off then do a Google search for brake servo pedal creep.

Could be a wheel bearing.

What’s the base vehicle..? All of my fiat’s brake pedals did travel a fair bit whereas the merc was solid….

If you have brake shoes on the rear pull the handbrake on and see if it's any better, maybe rear shoes need adjusting. Obviously when stopped!

Thank you for your replies, brake fluid was changed Sept 2021 at three years old. It’s the Fiat Heavy chassis discs all around. Pedals goes hard with engine off dips as soon as engine started?
