Evening all

Lately I've noticed that when I brake hard, as the car is getting down below the 20 KPH mark, the brakes seem to 'grind' and my pedal goes squishy.

Obviously this is kind of a problem, and Im wondering if anyone knew what was causing it?

Cheers

I think thats the ABS kicking in? Could be wrong though.
Does the pedal kinda push back?

Yeah, but I wouldnt have thuought I was braking that hard. Its a firm stop, but definately not a slam your brakes on expeirence.

What sort of road surface is it on?
Even if I loose a tiny bit of traction on just one wheel mine kicks in at low speeds.

I get it coming out of my drive sometimes. Theres a bit of gravel on the bitumen and the rear skids a bit setting it off. I have a feeling i need new pads on the front though.

Well, its done it several times, all on bitumen. I haven't noticed an abundant amount of debris on the road either. It definately effects stopping distance.

get your pads checked. I was gettign that too, and apparently i had really crapy pads on that got hard when really heated up and created a grinding noise..

Fair enough. I'll look into it.

I was under the assumption that if the pads were gone, it would grind constantly, not just at the final bit before the stop

Thanks for the help

sounds like ABS to me. When I slam the brakes hard when you get to lowish speeds the brake pedal will get a real crunchy feel to it.

Evidently I dont think ABS enages under 20km/h or so? Im pretty sure this is true because ive had to slam the brakes a couple of times before and will often have a tiny slide right at the end of braking,

Hey guys

your abs works constantly until the car has come to rest

also when the pads are low they will grind on and off as they place hard fillings at the base of the pads during the manufacturing process to alert you when your brakes are low before they grind metal to metal and cause seriouse dammage to rotors !

if your using a standard mitsubishi pad they did have problems with pads causing grinding noise through out the pad life as they went from the asbestos pad to a type of ceramic by memory and that caused the grinding !

In my experience when ABS kicks in pedal goes squishy and brakes make grinding noise.

Go and find out what ABS actually feels like now. The pedal will shudder under your foot and the whole car will shake as the brakes go on and off when the wheels lock up.

It amazes me that next to no one has actually ever hit the brakes hard enough to find out what it's like, I've done 2 defensive driving courses and several of the girls had crashed their small cars already, neither of them had put the brakes on hard enough for the ABS to come in :nuts:

Sounds like your in need of a brake fluid change/service. Squishy brakes can suggest you have a very minor leak in the brake lines, usually at the piston, and a minute about of air has entered the system.

As for the grinding, probably a glazed disc, u should consider a disc machine, and having the brake lines bled of the air.

also get the ABS looked at.. it might be failing and needs to be replaced/serviced.

You might need a bracket ?

I was told that the ABS doesn't activate under 40km/h :confused:

Hi Sevo !
Where you told this information by someone that is a mechanic or the service department or mitsubisi or a brake specialist or tell me it was info from someone who has a clue ?

Have you tested what that dork said? :P
Mine activates at about 5-10km/h while coming down my drive when the rear occasionally locks up.

no it is your Cruise Control that doesn't work below 40.

I have this same thing on my car - if you are not getting the grind ALL the time - your pads have not worn out.

This is a KNOWN issue with front pads, i believe it affects BENDIX brand pads, as they have removed asbestos from the pad - they are a tad too hard, so on some occasions, especially when braking hard, or if the pad gets really hot, you will get a grinding niose that sounds exactly like metal on metal, exactly the same as worn out pads

Apparantly you can buy a "spray" of some kind to apply to the pad to soften it a bit, which wil improve/reduce the amount of grind - check your pads, are the back (the part that you see from the outside of the wheel) of them blue? - if so, you have had a pad replacment done - thats when the problem tends to start - I have been through this with both my old TJ and my current KJ - I am planning on changing to DBA Slotted rotors and better quality pads to remove this problem!

If you pads arent metal to metal id say ABS too...:P

I have had the exact same problem with my brakes since I've owned it (3yrs) as you described. My car doesn't have ABS and my brake pads are only due for a change now.

Yes - i spoke to the service manager at our local Misu dealer - he is quite good to talk to, really does know what he is talking about, and doesnt speak bul**** - he said, yes, unfortunatly its a common problem, quite embarassing when your mates are in the car, but with factory rotors and genuine pads (bendix are genuine i think??) its a hit ans miss thing, some will do it, some wont, just the luck of the draw.

A disk grind and linishing the pads will help, but it will likely come back, and may even be different/worse than it was before.......he said spraying this stuff on them to soften the pads is about the only fix without going aftermarket stuff, but because it softens the pad, dont expect them to last as long.......

Finally got around to giving my KJ's wheels etc a good scrub last night,
pad backing colour can now bee seen. Got blues in the front, greens at the rear.

We acquired this car at 40,000kms 3yo so I'd be thinking they were the factory fitment?
Would be unlikely to be replacements as its also rolling on the original Bridgestone tyres.

My local service manager reckons the factory pads will go 60-80,000 with granny driving;
even with L'il Johnny mashing the brakes they wouldn't die before 40,000.

I'd say they are factory pads - i made the mistake of assuming if they were blue they'd be aftermarket, as mine were black before they were replaced, but they may hhave had so much crap on them the blue wouldnt show through.....so yeah, they SHOULD be the original pads, sorry, my bad......

Im glad I found this thread as I am having the exact same problem. Brakes dont make any noise at all until I am just about to come to a complete stop then I get a horrible grinding noise. So the only solution is to use this spray or get an after-market brake setup?

Might be worth taking the wheels off just to inspect every pad; I know I am pretty lazy
when checking pads, I just look at the top of the outer pad to assess what's left.

On a previous ride, our TN had a pad wear diagonally
- it had 4mm at top but worn to metal at the bottom.
