Afternoon - I'm after a favour and hope somebody can help. I have been reading through the threads for replacing brake shoes on the Fabia Mk1, and i just want to make sure that i am ordering the correct kit for our Fabia Mk1 1.2 HTP BME.

 

I've already ordered the plastic guides p/n 6N0609589, but not sure which pre-assembled kit to order. Can anybody point me to the correct kit? I only need to change the NSR.

 

 

I used TRW GSK1512

 

It comes with new wheel cylinders but if you don't want those they might do another kit without them.

Thanks! I only need to replace one pair of shoes on the NSR and i do need replace the cylinder, so i will contact them and check if they sell one side only.

NO !!!!       

 

you have to replace the brake shoes on both sides at the same time.....take pictures with your phone before you dismantle them---so you can see where the return springs attach to.

 

this will make it easier to build the new ones back up. 

 

BEFORE you remove the old shoes, pull back the dust covers at each end of wheel cylinders---if there is any brake fluid in there, then the cylinder needs changing  (in fact if 1 cylinder is leaking, then change them both).

Fitted the OSR brake shoes and cylinder this morning and so much easier to do the job after removing the hub - and yes i bought a new hub knut :-)

The NSR shoes are almost new. I have a receipt for the work done shortly before we bought the car - given that side a clean up though!!

The thing is, in the great scheme of things, this is a once only replacement within your period of ownership of this car, so I would have done both sides and tried to bin all the parts that I had removed, doing it that way means that this should be the last time you need to do this work, especially if you clean up all the brakes every year or every other year.

the reason it comes as a boxed set is so that ;

 

1. both sides will have equal coefficient of friction--so one side will grab before the other to cause instability.

2. the old ones on the other side are definitely a different diameter to your brand new ones that you have put on--will also cause early braking on one side, side effects as above.

 

 

I ask people a question when talking about replacing axle sets (shoes/pads/discs/shock absorbers) :

 

"Have you ever gone to a sports shop and bought just 1 worn out training shoe ? "

 

Also now that you have proved to yourself that you can do brakes shoes (some mechanics still struggle with them) ---go ahead and do the other side ?

 

 

Good feedback gents. Both sets of shoes and cylinders sides should have been replaced when only the NSR was changed just before we bought the car. Shame they didn't. However I couldn't see any reason to change the NSR shoes based on the condition and thickness of material left on the shoes. I am tempted to change the drums though......

So WHO changed just 1 side before you bought it ?  the owner I assume , Not a garage?  (If so its a sh*te garage that has no standards)

 

Its the "mix" of the friction material that causes the problem (not thickness/colour/age) --thats why you must do all 4 shoes, as then you KNOW that both sides will produce straight/balanced braking.

 

Sorry if I am hammering on about this but its important.

Whilst I agree with replacing both sides as a pair and there may be an different coefficient of friction between the old and new linings the above is not true.

You mean 1 new training shoe.

oh well,     but you get my drift.

if he fits new shoes to one side, then adjusts them up manually like i do (through a wheel stud hole) then the newer ones will be nearer to the drum, gives earlier braking on one side ?

No, only in the de minimis theoretical but not measurable sense and certainly would not be felt or affect the stability of the vehicle.

 

You need a significant amount of force applied to the brake shoes to create any measurable retardation, even if there were a big difference in adjustment when the brake shoes touch on the first drum the fluid displacement goes to the other cylinder (and the discs are doing the same thing) only when there is no free play left anywhere in the brake circuit will the pressure rise and measurable retardation begin.

 

Of course this all happens in a split second in an emergency stop situation.

 

What does cause noticeable instability is a sticking front brake caliper under light braking, the vehicle will veer to the side that is free moving.

 

I still carry a brake hose clamp that i made as an apprentice, it doesn't get used much these days but is there for when a brake cylinder seal leaks, more likely a caliper seal these days except its very unlikely.

 

Many a time in the bad old days I have driven for a few days with one rear brake clamped off until I could attend to it at the weekend, under normal driving there was no instability whatsoever and another driver would never know, under a full emergency stop the trajectory would change slightly requiring a little correction, no more than if one rear wheel was off camber or in standing water.

so you agree that one brake does get applied before the other ?

 

I am trying to get across to Garybaldi that as he now has the skills to change 1 side, that he should do the other as you are meant to ?

 

(as an apprentice we watched the mech, then had to do the other side while being watched?) and then we were told why we do both sides on a vehicle.

 

Then as we get more experienced we learn how the friction material mix is important/faults/causes and how to rectify ?  there are so many manufacturers  websites that we can access for free & get so much free information

from--direct from the people who make them.

 

 

there, marketing speech done& i'm finished with it !

I did

hmmm my car must have had unbalanced braking for 2 years

When I last visited the drums on the missus's Fabia, I ended up replacing only three out of four shoes. The fourth was probably only 25-50% worn, TBF.

 

The genuine Skoda kit o'shoes I'd bought from ebay was flawed on the basis that two of the shoes were identical instead of being mirror-images. Unfortunately I started on the O/S of the car where the parts were correct, and hadn't performed the wise 'pre-check' to make sure everything was correct in the parts I was aiming to fit.  So when I moved round to deal with the N/S only one of the new shoes could be fitted.

 

May well have been two years ago. Could have been more. 

No issues reported or experienced when I've driven it.  She's quite a reactive driver, so does a lot of what I'd consider unnecessarily harsh braking.

May revisit it  in the spring if I remember...
