Default Brake Pedal Travel? - 8th November 2013, 01:42 PM

Had my brake fluid changed last week as part of the first service - since then the pedal just hasn't felt the same!

The car still stops, but the pedal feels like it travels more before real braking starts.

Before I book it back in, what's the normal travel range?

Pop the bonnet open and the top off the brake fluid

You might have an air pocket

How much thread do have on your tyres that plays a part given the cold n wet weather

Topping up the brake fluid reservoir will not get rid of a air lock only bleeding the air out will.....

If a air lock the pedal will feel harder if you pump it!

But if you in anyway concerned go back as you can't take chances with brakes, better to be safe than sorry!

Also never heard of tread depth having a bearing on brake pedal travel! more like you could travel further as your tyres wear down as they can't clear the water as well if raining.....

Booked in, I'm sure it's not been bled correctly! There is the excessive (compared to before the work) travel and if I pump the pedal, it gets firmer.

Can't see how tyre tread would effect pedal travel, just the amount of braking required to stop!

Took it back today, there was air in the system, and it took them two attempts to sort it! Begs the question why the original technician didn't spot it on the road test!

I had my brake fluid changed recently by my local dealer. I'd fitted new calipers all round and did my best to bleed the system myself. Turns out that you can't do it with the new Mini's as its all controlled electronically. The "technician" basically connects a pipe to each bleed nipple, hooks up a laptop and lets the software do it for him. My technician was telling me that there are several places that you can get air trapped and the car has to be level in order for the system to be bled properly.

But like you said, this should have been picked up on the road test after the work had been carried out. I'd question this if they give you an after-service call...

As above, my pedal was back to normal last week (on the drive back from the dealers). Didn't drive the car over the weekend - took it out this lunchtime and the pedal was soft again! Drove straight to the dealers, who, to their credit, took it straight in to look at.

They could find nothing wrong (I was expecting a leak), but admitted it wasn't right. System has been re bled, and the pedal is stiff again. It's got me confused, can't think of any reason it would do that!

In addition, they found oil on the sump, so it's booking in next week to have that investigated !!!!
