Front Caliper Guide Pin Bolts

[greenhills]

Hi All,

 

looking at replacing front brake pads, the Haynes manual says that the caliper guide pin bolts should be replaced.

 

Can I ask is this strictly necessary ? On other cars I've never had to replace these bolts.

 

If so, is this likely to be a Citroen dealer only purchase?

 

It's a 2005 C3 1.1 Petrol Desire model

 

Thanks in advance

I have not replaced them and suspect most people would not unless they were damaged or had been overtightened and stretched. If you decide to replace them and do not go to Citroen, make sure you get the correct tensile strength which should be marked on the bolt head, something like 8.8 or 10.9. The higher the number the stronger the bolt. You may also find the thread is a metric fine one so the bolts are not readily available at a car accessory shop.

 

If the pads are due for replacement there is a good chance the discs also need replacing.

Hi Paul,

 

thanks - this is the first time the pads have been replaced as far as I know.

 

I therefore suspect that the original pads are in there and that the bolts should have been tightened to the correct torque

Hi Paul,

 

quick update - there was no need to purchase new bolts, the set of replacement pads contained 2 new bolts already treated with anti-lock compound.

 

These fitted perfectly. Think they were Lockheed pads.

 

Job completed last night.

 

Thanks again for the help
