Hi, upgraded the Leon brakes today, 312mm front & 256mm vents at the rear. Got the calipers & carriers off a TT225, stripped them, grit blasted them, thoroughly cleaned them, painted them & rebuilt them all with the lovely sticky red rubber grease. Fitted them today with new discs & pads but the peddle is crap & the brakes are non-exsitent :(. I had a pukka Blue Point vacuum job to suck the fluid through, no joy; tried the old fashioned pumping/bleeding method, no joy; then tried an Ezi bleed on the resevoir & the vacuum job on the bleed nipples - still no joy. :shrug:
Any ideas anyone?
Cheers.

is the pedal hard and your just not braking or is it squidgy and not doing anything? will most likely be a brand new setup alround and id say 30-50 miles before you start to get some bite but dont overcook it on fresh parts. if its a squidgy pedal check for leaks as sounds like youve rebuilt the calipers? and rebleed - what sequence did you use and did you bleed from all the nipples or just those on the calipers?

As above, make sure you have no leaks - I upgraded mine (fronts only) earlier in the year and tried to bleed them myself, but after 3 attempts at all 9 bleed points I gave up and took it along to local Skoda garage wher they pressure bled them - wot a difference :D

Job done! Air in the master cylinder! Put the ezi bleeder back on, opened up the bleed nipples (independantly) & fine! Servo assistance seems to be less now - peddle goes solid after a couple of pumps when the engine is running! Let them bed in this week & give them another pressure bleed next weekend - should be fine :)
Thanks for the replies guys :thumbup:
