I'm throwing this out to the experts and depending on what gets thrown back this thread may turn into a how to pad/disc replacement for 6th gens to go with the one for the 7th gens. Apologies in advance for the length.

At the HH meet yesterday I was advised about my front pads wearing unevenly and that it was probably a stuck caliper - I seem to be getting alot of these recently!

Anyway, this afternoon with the help of my father in law I had the osf caliper in question apart and the brake pads out. The pads are roughly half the thickness of the nsf pads. The caliper is one that was fitted as a refurb about 35k ago. Discs and pads replaced approx 20k ago.

We couldn't see anything that would be causing it to stick, but the pads themselves were very tight when fitted into the spring clips and we couldn't figure out how they are pulled back from the disc when the brakes are released. The pads were filed down a bit but they were still a tight fit & we didn't want to file them anymore. The caliper looks in good condition, the rubber slides moved freely and the piston looked clean. Everything was put back together again without a problem.

We checked the nsf caliper and it is still the original so is 10 years old and has done 124k, the 2mm or so of the piston that is visible is quite rusted but it still moves when the brake is pressed. The nsf pads are even tighter in the carrier than the osf, but it is only the spring clips that are causing this, as soon as they were loosened the pads moved freely.

The car doesn't pull to the side under light or heavy braking.

Questions:
Are the pads meant to be so tight when they are in the carriers with the spring clips?

Because they are so tight, how do the pads release from the discs when the brake is released?

If the piston and sliders move freely on both calipers what could be causing the uneven pad wear?

I have considered buying two calipers available on ebay and refurbing them myself - is this difficult to do and what is generally involved?

Or am I better off buying from Bigg Red (if they sell the calipers) - I can't send mine for a refurb as I need the car on the road.

Again, sorry for the lengthy post but I would appreciate any comments & help that people can offer.

Cheers,
Colin
 
Hey fella.

When the car was last MOT'd they obviously did a brake bias test. What were the results? And was there an advisory given on them?

The pads shouldn't be pressed against the disk all the time. After driving around for a little and pulling up at home (without slamming the brakes on :lol: ) are they REALLY hot? If so they are definatly binding. How easy do the wheels spin when the car is jacked up? Refurbing a brake caliper is not really hard to do, but if everything has been greased and is moving smoothly sounds like it could be a dud if it's causing problems.

You're best bet is to buy a new set of calipers and then fit them. Once the old ones are off they can then be refurbed and sold on so you don't make a huge loss on the new ones.

To be fair though 124,000 miles on a caliper ain't half bad! So it might just be time to change them to new ones.

Hope some of this helps. There is a video on how to refurb brake calipers on another site i go on. If i can find it i'll post it up here for you.
 
Hi Colin

What is the brake fluid condition like? I have heard of the inside of the brake hoses falling apart causing the fluid not to run as it should. Have you bled the calipers with a good amount of fluid coming out? Also, the pads should seat in the carrier snug enough so they dont have much play in them but also with not much resistance to stop them sliding back and forth. Personally, I would change the brake hose first on both sides, then flush at about 250 ml of fluid through the caliper and take it from there.
 
Also, brake fluid should be renewed regularly, I think its every 2 years and should be clear and clean in colour, not brown or black. Look towards the base of the brake fluid resevoir, normally the rubbish sinks to the bottom and the good stuff is at the top of the resevoir if you see what I mean. Have a proper good look at this. And I would also use genuine Honda brake fluid for this. Its very reasonable at about £3 for a 250ml bottle.
 
Hi guys,

Thank you for your replies.

There was no advisory at the last mot, but it was 20k ago.

The wheels don't spin easily, you do need to put more force than what I would think is normal, and yes the car was in neutral! The wheels wouldn't even do half a turn.

The pads are a tight fit when the spring clips are in place and I can't see how they could possibly come away from the disc, they really are that tight. If the tension is taken from the spring clips then the pads slide easily.

I haven't noticed brake fluid on any bill that I have had recently, so will get some of that.

I have just bought 2 calipers from Jap Parts so if they arrive before the weekend I'll have a good go at cleaning them up and swapping them. I'll fit new pads & fluid and I'll have a shop around for the hoses too.

I'll update the thread as I go.

Cheers,
Colin
 
Try removing the pad spring clips and cleaning out any corrosion that is underneath them.
I have just changed my son's civic's rear discs and pads because one side had worn the pad completely and scored the disc with the metal backing plate.
What had happened was there was a build up of rust under the stainless steel spring clip and it had trapped one pad and not allowed it to release, thereby wearing it away prematurely.
The other side pads were only a quarter worn.
 
Hi again,

I have got myself a set of calipers to refurb but am struggling to get hold of a refurb kit - I live near a refurb company and they apparently no longer sell the bits to Joe Public.

Looking on Lings, it only looks like I need to get part number: 01463S1AE02 - Caliper Set Front. It seems to include all the necessary seals and grease and it is number 1 on this pic from the Lings site

Does anyone know if I have to replace the slider pins or can they be cleaned up & reused? They seem a bit pricey so I would prefer to reuse the ones that I have got if possible.

Cheers,
Colin

Colin mate i can't see your link
 
The sliders can be cleaned, depending on the amount of soiling you may need to sand them. Then re-grease, and away you go dude.
