Hope someone can help.

 

Took my 05 mk1 vrs in today for handbrake problems, it wasnt engaging at all and aiming skywards. Cables were ok and came back with rear calipers. So i have have new calipers on both rears.

 

Picked it up and drove it a bit and felt a little laggy (if thats the word) , drove a little futher and ended up driving in 1st gear just to get it to move, went down to 10mpg. Nearly stopping as soon as i took it of the gas. Straight back to garage all 4 alloys cooking. messed with master cylinder and bled the both front brakes which seemed to retify it until i got home nearly. Struggling again, 20mpg, had to give 1st some stick to get it to go. Just checked and front alloys are hot rear are ok. Is this typical air in the system symptoms? Never had out like this before. Its going straight back to garage tomorrow but would like to know what the probable cause it. Going to be stewing on it all night now

. Will it be ok to drive it the 8 miles back in the morning?

Thanks in advance

 

 

 

 

 

I did my rear calipers last week for MOT as, like you, I had no handbrake and the pistons were seizing up so I had no pedal travel, modulation or rear brakes that were much use at all!

Anyway, a friend had a similar issue (not an Octavia) with brakes locking on and it turned out to be the servo.

What bleeding method did the garage use? I used a Gunson pressure bleeding kit with no issues at all. Apart from fluid over the drive when I didn't tighten the reservoir cap properly when applying the pressure from a spare wheel. My own fault of course.

Thanks, cant see how it be the servo? All brakes seened to be great prior to this.

Just drove to work and knocking it into neutral it would free roll nicely. However at 15 min of driving it went back to brakes sticking. Felt more the front than rear. Just checked front are succulently cooked rear ever so slightly warm.

When i took it back initially he had me depressing the brake when told and i think he was just undoing the nipples at each caliper. It this how it should be done?

Brake pedal is also very firm and not much travel at all

Just had a set a feeler gauges out at work, i cant even get a 0.001" thou feeler between any pad and disk. Now to me thats incorrect? What would you expect the clearance to be?

I heard that, with the manual, two-man method of bleeding, you can tear the seals in the master cylinder if you overstroke it. I don't know if that would cause your front brakes jamming on though. Quite possibly?

Great just come back to me and said they think the servo has gone!? Said i wont have car back until monday.

Doesn't sound like a Servo problem to me.
