just had full brake change to octy vrs front and rear...312's and bigger rear vented,,,,done professionally...prob is after 1-2 presse's of brake pedal the pedal is hard but with pressure kept on it sinks about an inch...is this the norm as everything is new? bled twice still the same....thx

Brakes will get hard if you keep pressing the pedal, or is this not what you meant?

sounds like it needs bleeding,they can be a real bitch to bleed

Shouldn't be a bitch to bleed.

With the engine off pump the pedal until its hard, hold the pedal down and start the engine.

The pedal should sink an inch or so.

They will need to bed in some. when you fitted the brakes I take it you either clamped off the brake hoses or kept the fluid level topped up?

Normal at idle speed due to mechanical vacuum pump for the servo. However if it feels different after the mod, likely need more bleeding. You may even need to get a dealer to do it, if air has gotten into the ABS unit.

mine were hellto bleed it took forever,mind you i did the full fluid change too

was done by a mechanic mate... when idling and i press pedal few times its hard at top...but with pressure applied it sinks slowly bout an inch ish...hasnt been used on road since conversion and he bled it again and still same...just wondered if its cos everything is new....

Could be, or if he has let the fluid drop further than the reservoir there may now be air in the ABS unit.

Hello,

May I ask, why did you want to press the foot-brake 1-2 times?

I have a Fabia VRS (its diesel of course) but continuous foot-brake pressure, will allow the pedal almost reach the floor. Try it when parked with engine idling, Skoda reckoned it is normal, but did replace master cylinder (no difference felt.)

Under normal braking I just have to touch the brake for instant response.

Octavia VRS have a diesel and petrol version I believe, which is yours?

so how would that be resolved ross? thx

What you describe is indeed normal for diesels with a mechanical vacuum pump for the servo. At idle firm brake pedal pressure will see the pedal going ALMOST to the floor. It is also partly due to the brake balancer valve not moving as the nose doesn't dip due to being stationary. So more pressure goes to the rear brakes than normal.

As always though, if any doubt about brakes, have them checked by a specialist.

thx for replies...
