  • Porsche Brembo's upgraded - Excessive pedal travel S2 coupe ABY

    Evening guys, girls.

    Trying to figure out a few problems since having my brakes upgraded to the 996 Porker refurbished upgrades supplied by Albert.

    Brakes, discs and fluid have been changed, brakes when pushed hard are immense but there is travel to get to that stage which is a little worrying..?

    Has anyone else found this, would the original master cylinder not be up to this type of upgrade and if so, can people recommend a replacement or point me in another direction??

    Thanks in advance,

    Check bleeding again,or the pump itself.I have 8 pot calipers on the front and 4 pot on the back and stock master pump still pushes enough brake fluid to keep the pedal in the upper region.

      Yeah I agree. Stock master can cope. Give it a good bleed. You have speed bleeders?

        speed bleeders? Now i google it,and its looks good...are they for Coupe quattro 20v as well?It could be used only on master cylinder and proportioning valve? On calipers not?because of hozintal/vertical position?

          the calipers where put upside down ! you cant vent them correctly now

          Change sides left one should be on your right and the other opposite. Vents up !

            Yeah you have to swap the cross over pipe with the bleeders. At this time it makes sense to swap in speed bleeders.

              They might crack.

              It is more easy to just swap the sides of the calipers

                Hi all, would this be causing an issue with the braking performance though? I'm not sure they finally got installed like this as the picture above was just testing fitment. Will check when I get back later??

                Albert, have you any other ideas to help with the brake pedal travel?

                Many thanks for all your comments..

                    Oh, I can't see any pictures. Whenever I have used 18z calipers I swap the pipe/bleeders as the pistons end up in the wrong orientation if one side is swapped to the other (L to R etc). Bleeders to the top dude!

                      albert, u cant just change left caliper for right caliper and opposite...Because if u have one piston bigger and one smaller piston in caliper, always is that smaller piston get the brake disc first...And i am not sure if you change sides it will not problem with bolt-on...I think always is left and right side calipers...

                        and calipers bleeders are always on the top of the caliper, isnt it?

                          Bleed nipples at the top. Small piston must always be at the leading edge of the pad, large piston at trailing edge.
                          They are a pain to bleed sometimes, I had an issue recently with some trapped air. Bleed at least 500ml fluid through each caliper. Also cycle the pistons in and out to shift any pockets of trapped air.
                          Also check the hub is perfectly clean and that the disc has no run-out when mounted - that will push the pistons back into the bores and cause a spongy pedal.

                              I don't think you need to loctite the bolts
                              You can reuse OEM bolts
