Brakes Sticking??

[MM's Talon]

About a month ago I put bigger brakes on my 90 gsx, they came off a 92 gsx, with the bigger rotors, and it has good pads ect.. I had no problem with them after I bleed them and yeah all good, yesterday i was driving around and I was listening to music and when the song changed i heard like a dragging sound, so i pulled over. First thought was hub bearings, tried to move the wheel and it seemed okay, checked the rotor and was a bit warm but no marks from dragging so i went straight home, by the time i got home i noticed that my rear and front brakes driver side brakes were dragging, i was thinking either abs or that valve (forgot the name my mind went blank) but idk where to start. help me out please.

Sounds like you have a possible bad caliper.

Yeah sounds like the piston is not going back in..I had this problem a couple years ago..All I did was take the piston out, replace the seal, and it has been fine ever since..

How many miles was on the 92 when the calipers were removed? What condition were the calipers in?

It is very common for these calipers to seize and/or not retract. It might be time to take the caliper off and see if it is sticking, if it is sticking or damaged then a rebuild is needed. At this point it might be cheaper to buy a rebuilt on than to buy the parts and rebuild it yourself. They are just so readily available they become so cheap.

http://www.dsmtuners.com/forums/art.../347494-how-rebuild-front-brake-calipers.html: procedure is for single pistons but its the same for two piston calipers, just double the work because of the other piston.

When I did my big brake upgrade, I got two rebuild 2 piston calipers from rockauto for 100. 2 years on them and then I switch, never had a problem while I had them.

goodluck

There was about 90000 on the calipers, and about 180xxx on my stock rear, but they were all fine until yesterday, i oiled them and made sure they werent seized, i mean why would my rear stick too? that makes since that ill have to rebuild the caliper but i don't get it about my rear, could it be the pin? the one the caliper slides on

My front seized on me at 97,000 and my one rear at 99,000. 2 thousand miles of each other.

The front calipers would not cause the rear to seize in any way.

I wouldn't look at it as "they both seized up at the same time" there is no coincidence, just timing of how everything is culminated. They might be both sticking because they are really old and have a lot of miles on them, and failed around the same time, or the install maybe caused one to fail prematurely (although 90k and 180k miles is a lot on calipers, especially in spirited driven cars).

it could be the pin, but less likely, you can always add grease/lube to the pins, maybe get new boots for the pins.

But like I said, at this point if you know they are failing, rebuild or get new ones.

My rebuild of the caliper literrally cost dollars to do..It was just one seal, which I got at the local auto parts store..

Mine seized up ohh I can't say for sure milage but it was under 100k..Cause I just put 100k on my car..

The seals get old, It happens..

 

[MM's Talon]

Okay guys thanks alot! I'm going to buy rebuild kits for all four you know, because if it happen to those two don't want to chance it, thanks guys ill keep you updated and see if it worked!

 

[Bud92gsx]

That's a damm good idea, to just rebuild all 4..I just did one to get by..And havn't had another one fail on me yet, thank god..I got lucky with that..

Your right Bud, it cost dollars to rebuild a caliper. Its a rebuild kit, there are definitely more pieces to a proper rebuild, seal, outer boot, boot ring.

I am all about DIY, but if you look at calan's write up, certain tools are needed to do it the correct why and not everyone has access to them. Compressed air, drill press or hand drill etc. The piston should be cleaned and have a proper finish to the wall as an example. That's why I suggest buying rebuilt ones, they had all the necessary work done to them to allow them to be warrantied, the proper rebuild.

Hes got the write up now and the how to, so more power to him if he can do it himself.

I just feel that half assed work leads to half assed results.

 

[Bud92gsx]

Ohh you can get a whole kit for rebuilding the whole caliper..Gotcha..

Well I did not get a whole kit, I must have been lucky again..To it just to turn out to be the piston seal alone..The boot was old, and probably cracked..Not allowing the piston to return..so I must have just gotten lucky..
