I had a brake caliper replaced a week or so ago and today was only the second or third time I have driven the car.

I ran the lioness to the local supermarket and after shopping I let the handbrake off and reversed out of my space

as the reversing sensors started off the chirping, I put my foot on the brake and to my alarm the pedal sank nearly

to the floor! the pedal travel remained long until I had pumped the pedal a couple of times.

What on earth could cause this? I assume the brakes were bled after fitting the new caliper any ideas please, I am

more than a little rattled by this.

air in system?

Keep an eye on the brake fluid level also.

All other things being well, fluid levels, no leaks, no wobbly wheel bearings. A brake pedal that randomly drops to the floor is a sign that the master cylinder has a fault. Always found that its best to just replace it than messing around diagnosing and bleeding and hoping it will go away.

Take it back and get them to check it over.

...leaving a more generous gap than usual in front of you on the way...

 

Was it a front or rear caliper that was replaced?

It was the front (driver side) caliper that was replaced. I really need to know

possible causes so I can get this fixed so's I can get to hospital appointments

The money is on air in the system and whoever did the job needs to correctly bleed the brakes.

But unless you totally trust who did it, have someone competent to check over the work. 

Maybe even bleed the brakes.

'You decide!'.

I would have it checked now would appear to be air in system.

There is nothing more trouser messing than pedal to floor when you really need it I speak from experience fortunately did stop.

This was in days past when I never paid more than £30 for a car that would last a few months.

Well I took it in this morning, I demonstrated the excessive pedal travel,

apparently it is a vacuum system and they all do it.

To prove the point I was shown to the showroom Yeti. I started it up and

put my foot on the brake pedal, good and firm no unmanning plunge for

the floor, just a slight creep after a few seconds. I was driven home and

they will investigate further.

They do a good number in blarney it seems

I have it back! the servo (vacuum side of the system)

was tested and the system brake fluid bled.

There was a little air in it, but the pedal is nice and firm again

I would report what they told you, ( they all do it ) to Skoda UK. They could have sent you on your way with a potentially lethal brake fault. If a brake pedal suddenly goes to the floor there is a major problem, and no way do they all do it. I would be livid that some Techie hasn't done his job properly and put your life at risk.

I am waiting to see if the fault returns, then I shall involve an AA engineer,

they have just changed workshop manager and it would be too easy

for the outgoing man to be a scapegoat.

The problem with a lot of garages nowadays is that they don't carry out a road tests after repair, or carry out a rolling road brake test in the MOT bay.

 

I would not of considered giving a customer his vehicle back without testing it on the road first. Today most are just fitters and not City & Guilds certified mechanics.

 

If you firmly apply the brake pedal, then start the engine, when the vacuum is established you will feel the brake pedal drop, this is normal in all servo assisted brakes and should not be used as an excuse for pedal movement.

Hope its all sorted out.

 

If you still think the brakes are not as good as you think they should be,take your car to a local mot test place and ask for a full brake test only and get the corresponding paperwork.

 

good luck.

I drove the car on a road test with the mechanic alongside me, the

brake is working the way it should, any twitch out of the "normal"

and it will go back, the tip about the MOT brake test is a good one

but will they let me take it away if it fails? Health and Safety and all that

 

By the Way they do MOT's.
