irregular front brake wear

well I did my first (and only) brake job around mid oct/early nov. I have one side that is grinding the warning (and now since its january I think its nearing metal). what I cant figure out is why its only on one side (passenger). I know I did the break job myself, but I had someone, my mechanic, look it over and hes said i did it correctly.

I had asked if the brakes needed to be bled, but he said that they dont require it (and that he doesnt do it to his own mitsu - a early 90's galant, i think). I used to bleed the brakes on my '90 toyota 4runner.

was he wrong on this? my front driver side is wearing down correctly is there is still maybe 15k miles left on it... but my other one is almost completely worn down, and I cant figure out why...

1. Remove brake fluid fill cap.
2. Remove old brake pads
3. Push back calipers.
4. Install new pads.
5. Replace brake fluid fill cap.

If you didn't drain the brake fluid, there's no reason to bleed the brakes. Bleeding gets rid of air in the lines. Unless there was air in the line to begin with, it should be fine. Your problem is symptematic of air in the line. It couldn't hurt to bleed if you know what you're doing.

I think air in the line can be what's making one side different than the other. Can you just start over again?

when the caliper piston is pushed, air will circulate back and will get stock inside the reservoir. try to release some of that air by un-capping the resevoir. just changed my pads, it took 11 months for my pads to be replaced. ( since am' racing the son of a..) i, used genuine mitsu. pads last time, now am' using kragens.....i, dont know but kragens pads aint workin good, compare to mitsu's.brake pads. i, paid $60 something for the pads that spits dusts already.

by the way, its better to bleed em' now...(while you on it) or ya'll goin to regret it soon when you get done installin pads.

no choice, I going to re-do them in a few hours.

yes this is exactly what I did... i hope this doesnt end up being a time consuming job (weather is going to be bad for a few days, and I need this done asap)

yaw good to go....but again, its better to bleed the damn thing. sometimes regular pads replacement causes a tiny pressure ( when push piston back to the housing) and all will experience right after the installation. and i, hate it when i install something, only to find out afterwards that the part /parts aint working or defective and need to be re-install. so, check on it carefully (esp. the pins, sometimes its pain in the ass) when you push the piston back to chamber, make sure resevoir cap is tighten. and dont get kragens pads, too expensive and aint workin good.

what about resurfacing rotors. I was always told not to resurface them if there weren't any grooves in them. This was back on my 79 camaro. I recently read in a newer non mitsu manual to lightly sand the rotors to remove any glazing, etc that may have occured. I have always done my own brakes and never had a problem. I did my wifes brakes on her 04 buick, didn't turn the rotors and her brakes were acting up a month later. took it to the shop and they said to always turn them. Her rotors were REALLY grooved, but weren't when I installed and I kept them free of debris. Did you guys turn, or just replace the pads?

Big Pun...any updates?

did them the old fashion way.

an afternoon and a few beers!

LOL

well no beers, but the rotors were still nice, no grooves. so swapped out the pads (and there was significant amount more wear on the passenger section).

outtie drives smooth so far. I did hear of some NZ/aussi outties experiencing this problem as well... maybe has to do with the ABS?

anyway, should anything occur within the next few weeks I'll do another update.

so future adivce: bleed the breaks.

you dont have to re-surface, unless your rotors that bad.( warps') i, basically replace the pads, then clean / check rotors for debris. i, use alcohol to clean the surface. if, theres noticeble un even rotor surface, then its time to re-surface it. if it is good to go, dont mess with it.

Good, I hate taking my car to the shop and "donating" money. Good point, maybe it is the ABS systems that cause the uneven wear and grooving in the rotors. Anyone able to confirm?

it is the ABS system, i own a 03' outtie...since then, i replaced the pads 3 times. no doubt about it, somethings wrong w/ the ABS. and am' getting tired of it.

yes I just had a 'neighbor' (6 blocks down) come and ask me about this. I guess he figured I knew what was going on when I changed my brakes and threw the worn pad and curse at the caliper LOL

just came back from the neighbor's. I found this to be very weird. not only did he have alot of meat on the pads, but his rotors were the source of the noise.

I took a look at mine again, and it does seem like it could use some resurafcing, but at $25 to turn it, i might as well spend a little to get a new set.

damn you car, stop eating my money on stupid problems

starting to be glad I don't have ABS....until I slam on the brakes to avoid a collision that is :)

I just did my brakes(front)- actually had to take it in to have them done due to the lack of time during my work and temporary class schedule right now. I have been checking my brakes monthly because I knew they would need to be done relatively soon. Last month it looked like three more months easily. However, the passenger side caliper is not working properly, it's not fully releasing says the shop and evidenced by the pads. One pad was worn down to the backing plate on only half of the pad, it was really strange. I'll be off to the dealer to see why the brakes are pieces of shi$ on these cars. I was told the caliper will need to be replaced at the latest by the next brake job, sooner is better though. I'm hoping Mitsu will eat the cost due to defective product.

I went to meineke the last time...and I've had much better luck!!!

pads wearing evenly on both sides still?

lolz....dang!!!!

Yup....I can't believe how well these pads are doing. Maybe it's because I got different rotors?

Going to pick up my car from the dealer now. They had to replace the caliper, one of the pistons wasn't releasing. The lousy bastards wanted me to keep driving 100 miles per day on it like that. Who cares if my rotors get F'd up. Who cares if my brakes aren't as functional because they are getting too hot. Who cares that it stinks like a semi under full load riding his brakes down a hill. Damn, Mitsu service is SECOND TO ALL. I had to argue for 20 minutes to get a pos loaner. Okay, I'm done now.

THAT JUST SUCKS! See if you can go to a different dealer. The first Mitsu dealer I went to was so bad...I went to another and I get treated like a king. Plus they love all the Mods I've done!!!!

uhh well, we have to admit....outtie's brakes system sucks!!
