Sirion brake discs


Hi all,

I have a 2002 Sirion 4 Trak which has been great but some time ago I noticed that my nearside brake disc gets significantly hotter than the offside. The brakes have never been sharp but it passed its MOT no problem and doesn't pull significantly under hard braking but there is a noticable pull when braking softly.

The car has been checked by my regular garage who changed the nearside caliper and discs on both sides. It has also been checked by by a Daihatsu dealer whilst in for a service and as yet there is no explanation. I was wondering if anybody else has noticed this and if so is there a remedy.

The other thing I have is a constant pull to the left. This was improved by getting the wheels aligned by a specialist company but has never been totally cured. I have put this down to a characteristic of the car but I am thinking it may be linked to the above problem.

I would like to get it checked by a brake specialist but don't know of any so if anyboy knows of one in the Midlands I would appreciate the tip.

Many thanks for your help.

Don't like the new shape Sirion much.Sorry.

Pulling to one side is usually caused by the Caliper (On the offending side)not releasing the pads enough to clear the disc, and that would explain the extra heat on the offending side as well.
But you say you had a new caliper and discs fitted - so this is very strange indeed.

I have had a fourtrack (Nice Car) and I now have the Rally 4.(Even Better)

Both have been fitted with new discs and pads but the calipers were just cleaned up and copper grease applied to the touching parts. Neither of these cars has ever pulled to any side. I can only think there is not enough lubrication in the right areas to make sure the caliper can release properly.
You also say it pulls to the left all the time.
Has this car been in a bump at any time on this side?
Could be the suspension on that side.
But it could also be the caliper not releasing the pads enough.


Sorry, thats all of what you say - Points to.


ps - Is your steering wheel Straight when you are going straight?

Thanks for the response BobF.

I think I misled everbody however when I said that I have had the discs changed, I actually meant pads. The discs are still original but I don't think that is the issue here. In fact I think your conclusion is pretty much what I thought also. All I need to find now is a brake specialist to give it the once over and free up the caliper.

Regarding the pulling to the left I don't know if it has been in a smash as I have only had the car about 1 1/2 years. In answer to your question, the steering wheel is straight when I am going straight. It didn't used to be but the wheel alignment specialist sorted this out for me. Hopefully if I can get the brakes sorted out this will cure that problem also.

Thanks again,


You no good with your hands !!

I can send you the full exploded Brake photo's etc.

Beleive me when I say the job is fairly easy as long as you are comfortable with handling tools.

A good clean and the correct grease in the right place should do it.

DIY disaster zone

My attempts at DIY usually end in disaster! Plus I do not have any safe equipment to jack the car up. Having said that if it is as easy as you say it is I could give it a go. What will I need to keep the car safetly off the ground?

In answer to your final question I live in Nottinghamshire.
