just need some knowledge on my rear brakes. it seems the rear brake are not engaging completely. the rotors are not smooth and shiny, but rather rusty and bumpy.

after driving for about 30 mins, i can't even touch the front rotors their so hot but the rear one are hot but i can touch them. it also seems that when i pull the e-brake i would have to get it all the way.

is this the brake pads?rotors? brake capliers? or do i just need to replace fluid and bleed.

this is on both of the rears. i can take pics if this would help. thanks

 

Post pics, we can help.

 

This is the caliper slide pins frozen and not releasing most likely. You will need to get new hardware and relube them or rebuilt calipers I imagine. Mine are exactly the same and I know with the harsh winters these calipers stiffen up and the grease vanishes and rust builds up and they start "seizing"

 

You should pull the rear calipers and inspect them for rusting, broken or damage boot and/or seal, and potential leakage. If they are damaged or not in good condition replace the entire caliper (less hassle than trying to rebuild them). On the rear calipers you can try compressing them and see if they move. If they don't move then your calipers are seized.

**To compress the rear calipers you must rotate the caliper piston in a clockwise direction. Needle nose pliers to the hashes on the piston surface work fine in doing this. Normal caliper compression does not require much force to compress in this manner.

If you can compress the calipers, then I recommend reinstalling the calipers and and flushing/bleeding the brake fluid out of the system.

**Brake bleed procedure is very specific on which caliper to do first. Order is as follows:

1. Passenger rear
2. Driver front
3. Driver rear
4. Passenger front

 

I had a hanging caliper that ruined my Hawk HPs and a Hawk slotted rotor.

I took it off and broke it loose, screwed the piston back in and it seems to work okay, but the damage was done.

I got a set of Wagner rebuilt calipers from a buddy of mine than works for Federal Mogul (Wagner's parent company)

Had them both done in about an hour.

I used new Wagner rotors, but I'd love to see if they can cut the Hawk and get it back on. They were damn good brakes and rotors.

My advice is to go for a new set or rebuilts. Our calipers have a long hostory of seizing.

Good Luck.

 

it looks like this on both rear rotors

 

Your pads are seized in the sliders. Take the pads and sliders out, clean the caliper body where the sliders sit of all rust, clean the sliders, and clean the pad tabs (hitting them with some sandpaper is a good idea too). Apply caliper lube liberally to the sliders and pad tabs, reassemble.

For some reason, the rear brakes love to seize.

 

i replaced the sticking caliper and now the new one is frozen, help!!!
