Brake Question
 

so i suspect i have a stuck caliper, symptoms are bad smell, both front wheel full of brake dust and back wheel barely any dust, change my pad once a year or two


so i did some brake job today but i was curious about something, are the brake pad suppose to be lock on the rotor when the car on park ? or they suppose to be fully retracted when on parking ?

If your caliper is stuck and pads are dragging, you should see blue rotors from heat of the dragging brakes.

You should be able to spin the wheels in the air. Excessive brake dust can be normal depending on the pads used.

They only float a couple 0.001 off the rotor when spinning.

A stuck caliper will wear the crap out of the pad/s affected.

Make sure to remove quide pins using 7mm hex and spray LOTS of brake cleaner in there to clean out the goop that COULD be in there. Then use a light coating of AGS (Napa) Syl-Glide before reinstall.

Just did all the stuff you guys says this morning, but now the break feel spongy, fluid level look same level before and after brake change(ya i open the cap before retracting) so wtf? No need to bleed right? Since i didnt open any brake lines

When was the last time you flushed the brake fluid out?Sent from my SM-G950W using Xoutpost.com mobile app

my garage did it january 2020


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

Sounds like air got in the system some how. I would bleed them again. Are you100% sure there is no leaks?Sent from my SM-G950W using Xoutpost.com mobile app

Spongy = air. How immaterial.

If not in the abs block you can use pressure bleeder. You said caliper stuck, if the un-sticking process damaged a seal you'll be looking at new/refurbished calipers.

If no leaks just need to bleed.

seem like no leak, will look again tomorrow , will it damage something if i drive with air in the system a couple week? garage are busy here
