Sticky Rear Brakes...

[dantheman68]

A few months ago i changed out my rear caliper brackets because the inboard pad of my D/S rear was worn to the backing plate... i also got new rotors and pads since the pads were obviously done for.

now after the instal, before i jacked the car down i knew something was a bit wrong since the D/S wheel spun freely and the passenger side was spinning, but obviously restricted... moreso than the other side anyway...

i hadnt driven it since then because i am at college and i dont take my car with me. i went home this past week for spring break, and ordered some SS brake lines This Sunday i took my SHO down and the plan was for my dad to drive it back... after i got off the freeway i smelled something burning... yep you guessed it.... brakes... EXCEPT now it was the rear D/S... and there was visible smoke to confirm this... is my problem the brake lines?... my dad drove it home and proudly said he didnt use the brakes for more than 95% of the trip and just timed his stops and let the car slow itself down and said that the brakes were no longer hot...

ive also heard about the ABS modulator screwing up and locking down on the brakes if fluid is pushed back into it during a pad change, or when the caliper is compressed... is this possible?


now lets see if SHObros can get my SS lines here before the weekend since i ordered them on the 12th

Sounds like a sticky situation Dan, So that was your smoke sho that i saw go past the dorms sunday :laugh_ti: anyways when I got my car the P/S rear was stuck open and I bought a new caliper to find out it was the lines, this might be the issue with yours only yours isn’t allowing the fluid to go back through the line, when you press your breaks the MC has a lot of pressure and can expand swollen lines enough to let fluid through and then the lines close up leaving it in the stuck on position, I would see if the lines fix it otherwise good luck Also was it doing this all spring break or just your drive back to UWM? Did you bleed them at all?

 

[dantheman68]

just the drive back... no i didnt bleed them... ill try to do it before saturday though... i hope my lines came today or will tomorrow or ill be SOL... i cant belive shipping is taking so long

The brakes on these sho's suck!!! While i now drive a gen3 my son still has his 2nd gen. The calipers stick and the pins that hold the caliper get corroded and will not allow the caliper to move. check those as well. you can buy new pins or sand the ones you have and apply **** to them. lots of ****! the 3rd gen aren't much better as i have had to **** the pins twice in one year time.

new pins come with the brackets... so maybe you misunderstood, but they are new

OH and im well aware that Ford's brakes suck... ive seen it many times firsthand *shakes head*

Thats odd that it just happend on the way back, that makes me think that your best bet is the lines, i would do a full flush and new lines when you get them and then see whats up, other thing would be a sticking e-brake but i dont know, and yes fords brakes suck i remember coming in to my drive way in my GL with smoke going past both windows and i had to jump out and run for the hose as flames came out from my front brakes

i just got a great picture in my head...


yeah i had a buddy with a contour thats rear brakes were locked up... quite the thing when he pulled it into the shop at highschool on the concrete floor :laugh_ti:

i think its a combonation, since all of the repairs i have done so far have been several things causing one problem of which i find out after fixing the most obvious... then i have to find the less obvious... like the BDA required me to change my fan speed sensor too... and the secondaries needed a new secondary controller and a PCM... and the clutch... well the one i put in was defective... the tranny that blew the diff pin i had to replace with one that had RTV sealing the case (thus needing a new synchro and blocking rings)...

and im sure the list is not complete yet...

Yeah I almost stopped and just let it burn, i should have, would have been alot easier but then i would have had to scrape it off the driveway

Did you break-down the calipers and check to see if the pins were actually greased? In two sets of rebuilt calipers I've purchased in the past (one Ford, one GM), they failed to grease the pins on both sets of brackets. And there's been more than several occasions where I've seen the grease barely cover the slider-pin on at least one pin in a preassembled caliper set.

If you find the pins have begun to freeze-up from sitting most the winter, replace the pins and pick-up a high-quality synthetic caliper grease - it's $9.98 for a large 8-oz. bottle at most auto parts stores. I would recommend either the Permatex (Advanced Auto - $9.98 for 8 oz.) or VersaChem (O'Reilly - $11.99 8 oz.) synthetic greases. While AutoZone carries CRC synthetic grease for $9.99, it is a dull black-gray grease compared to the green Permatex and blue VersaChem greases, which are semi-transparent and allow you to see when rust begins to develop.

These pins should be inspected during every brake service, even if the service is to simply check pad wear. It's cheaper insurance than an oil change....

they were replaced less than 3 months ago... i hope to **** they arent siezed already... but ill check em anyway and **** them up... my symptoms point to brake lines, but they are kinda wierd in that they "trade off" sides every once in awhile...

The rear brakes are on independent circuits. In the absence of an ABS pump problem, the only two common components between the two are the rear proportioner valve and the emergency brake cable. How often do you use the emergency brakes? A quick check would be to remove both emergency brake cables at the caliper and see if the problem stops. A bad master cylinder can also cause calipers to temporarily freeze-up.

I do sometimes have to take a flat screwdriver and a hammer to push my e-brake cables out though the slicers opening, on the side of the road. I'll **** them when weather gets warmer.

 

[dantheman68]

i guess ill have to look at my E-brake...

 

[frosho]

i bet it's the rear hoses going from the hard lines to the calipers. it's happened to me, and i've read about several other cases of the same thing since i replaced mine. same symptoms... smoking rear brakes, etc. after replacing calipers twice, i finally did those lines and the problem was solved.

 

[Storm-Chaser]

That was already discussed above (hoses). And if it were hoses, the "trade off sides" is not something commonly associated with bad hoses.

Did you try un-doing the emergency brake cables yet?

Did the stainless line kit show up yet?

Please post back what you find....
