Brake disc temperature

Featured Replies

OK!

Here we go.

Just fitted a new caliper on rear rhs.

It was full on and fully seized.

It was a warning on my MOT in June 2016!

Anyway all done and dusted.

I decided to test my other brakes to test for early signs of seizing as I thought " One down, how many others are ready to give up the ghost"

Perfectly normal paranoia!

Drove 5 miles without braking at all.

All the other discs were at ambient.

The rear lhs disc was above 100C.

This new problem caliper wasnt seized  when I replaced the break pads, done at the same time as the rear rhs caliper change.

 I must admit it did take a little wellie to recess it with the proper tool though!

Am I looking at another caliper on its way out and just bite the bullet and change it?

Any observations, experience will be handy

To be on the safe side i would change the caliper as Brake's are the most important safety system on the car. Also a good idea to clean the carrier and clean all the sliders as well as these can sieze as well.

^^^ sounds sensible............use this indication as that it probably will fail sooner or later and as sods law states, probably when you need the car most.

 

I would say replace (or strip & clean as you have the rewind tool) at your earliest convenience.

Thank you for your input.

I took a measurement of the discs using an IR thermometer.

After a 10 min drive it was at 140C, while the others were around 40C!!

I thoroughly clean the whole brake unit so other causes are highly unlikely.

Just bought the caliper so I can get it sorted by the weekend.

Thank you both again for your replies.

I have had a similar problem in both rear calipers at different times. Both problems were related to brake caliper cylinder. Take it out completely and look inside, clean it. It might be seized and the mechanism not working correctly, since the caliper wont release the pads.

Have you checked the cables, if they are sticky it prevents the caliper from returning fully and causes the pads to drag.
