Does anyone feel that the brake pedal is soft? I press it slowly and its soft but when i press quickly its harder any solutions? I recently replaced my rear calipers too

 

Probably some air in the brake lines. Try bleeding them.

 

when I replaced the rear calipers I only bleed the rear two that i replaced... I bleed them until there was no more air coming from them... so I might still have air in the system....

 

It's definitely possible that some was missed. Maybe a flush on all the lines would be a good idea, just to be safe

 

hmm I think about to change my front brake pads... While I do that I'm going to flush the brake fluid... after driving it for God knows how many years with seized rear calipers I'm sure I've been using the front calipers 100%

 

I have the same problem. Its squishy bro. I recall a moment coming down from grapvines on both la and bakersfoeld side and I would get a vibration when I broke really hard on a decline. Have you thought about resurfacing or replacing your rotors. Maybe drilled and slotted. I have but I have not done that yet

 

haven't replaced my rotors yet.... I've replaced the rear calipers and that was my main problem... brakes work okay... they just sort of have no feed back pressing it like 1/8 of the way even know I'm decreasing in speed, but they seize in the cold still... maybe your rears calipers are seized too? Or maybe prolong aggressive driving has caused some brake fade.... vibration is most likely abs kicking in... was the traction light going off??? I heard I shouldn't resurface my rotors... I'm not sure when the last time they were changed or resurfaced... I only started driving this car about 3 years ago and started noticing these symptoms...
