172 updated brakes - 'dead' pedal travel

[docdale]

Would be grateful for some advice please.

Just updated the brakes on my 172 with ktec front and rear kits (brembo HC discs and ultimately pads front) with braided hoses and updated fluid.

They squeal (expects initially) and stop very well (as expected) but I now have about a couple of inches of 'dead travel' where nothing really happens when initially pushing the pedal before the brakes then work really well.

I did not have this before the new brakes were fitted. There is no air in the system as been bled correctly.

It feels as if the pedal travel needs adjusting but I am not sure this is possible?

Whenever I have had updated brake kits fitted to other cars the pedal usually feels very solid and hard from initial touch of the pedal but this seems different and I am not sure why?

Thanks in advance

Could be the pads you have on mate, I've just fitted DS3000 and they're similar, not much happens then they bite like nothing I've felt before. What pads are they again you have fitted?

 

[docdale]

They are optimax pads.

It simply feels the pedal has no resistance at all (almost feels loose) then feels like the brakes engage and then the braking is fine/pedal then firm.

I can't work out why there is this initial dead space.

Try re-bleeding. Does the pedal go hard after a few pump with engine off?

 

[docdale]

Will try that. Thanks

Yeah, does the pedal stiffen up with the engine off after a few pumps on it?

It could also be they need re bleeding. After bleeding them once and driving it about they can need re bleeding.

Try taking it for a drive and bedding them in properly. Mine felt exactly the same when I put the megane callipers on. Now the brakes have bedded correctly they feel excellent. Biting straight away.

Yep he pedal stiffens up after 3 presses so looks like needs re-bleeding (despite garage saying definitely doesn't). Think I need to go somewhere else! Thanks for the input.
