Not my first issue, but definately the worst. Heres link to previous:
So first let me describe state of my rear brake. Its shite! But it was worse last year when pads werent retracting upon brake release. Spongy, this season, (after plenty of bleedings) but due to that poor pressure, the pads seemed to be retracting/ releasing. :p improvement from last year, and i dont use it on the road.
Brake pedal falls against pushrod causing activation of rear brake switch when sitting/ riding. So ive been holding pedal up with toe, allowing MC pushrod to fully extend/ brake switch unactivated.
I lengenthend both studs from pedal (shortening play to MC and increasing distance to push/activate brake switch)
Riding this morning, in 75degreeF weather, the pads mustve rubbed, then seized and i pulled over to find pads smoldering, no flame, but probably warped my disc already. (10 MINUTE RIDE NOT USING REAR BRAKE)
So my question, WTF is my issue? Sponginess after having bled and renewed brake fluid. New pushrod, caliper seals, and pads last season. When sitting, weight of pedal depresses pushrod about 3mm. When pedal is raised pushrod extends out slowly, drop the pedal and it depresses again 3-4mm. I checked last season for obstruction in either of the holes in MC, none apparent (air flow possible).
Do i need new MC or pushrod? New caliper? Replace brakeline? Replace caliper seals?
