Brake Question

[andrewwynn]

Only real damage will occur is if you lack of breaking power cause you to crash. I would use the slam on the brakes and gravel method to test if all the wheels are working properly. Pull the ABS fuse then find some gravel or sand and slam on the brakes compare how long the skidmarks are. if the spongy corner still can lock up the break you’re pretty OK.

does it make sense that the pedal feel different now that my caliper are not stuck ?

100% makes sense. Does the vehicle still stop.as.fast? After I did full brake rebuilds all around, my pedal moved faster to the floor and felt softer but it was cause there was less resistance cause all guide pins were lubed and all pistons were rebuilt with new brake assembly fluid.

There are at least half a dozen threads on xo in the past 18 months where old school brake bleeding was unsuccessful. Everybody eventually uses a pressure bleeder. I bought mine before I tried because I read the threads first.

Dont know if i did the right way, but no bubble at all, i did

Bleeder close , dad push brake , then open bleeder wait a few second no bubble so close bleeder, release brake pedaal.....and repeat

There has been talk that suggests that manual brake bleeding over-extends the master cylinder (pushing the cup/seal deeper than normal into the bore) and damaging the master cylinder seals (if the bore is corroded).

This could lead to a poor master cylinder seal and a soft pedal feel.

I've manually bled car brakes for years and never had an issue but I vacuum bleed brakes now after reading that!!! It's also easier and a one man job - like pressure bleeding.
