Need Help on my brakes Lag2 dCi

Hi guys,

1.9dCi Lag 2, 2001 Y Reg

My ABS light came on today as did the orange sevice light (SERV), i nted that the Stop light did not come on, therefore i'm thinking that this could be pad wear on the brakes ??

i have noticed that the handbrake does come up a bit further than it did before,,, everything still works well

Here's the questions.

1. Can i replace the pads on the rear myself (not a mechanic, but basic knowledge)

2. Could it just be requiring adjustment ?

3. i was pricing pads on EUROCARPARTS, but found there was 3 different lag models for my car,, how do i know which one i have ?

they are :

Laguna II - 1.9 dCi: F9Q750 F9Q756
Laguna II - 1.9 dCi:F9Q752 BG0E
Laguna II - 1.9 dCi:F9Q754 BG0R

many thanx as usual for all your input and advice

Hi to change the rear pads is easy enough.
But you will need to wined back the caliper piston fully.this also resets the hand brake levers.
Dont forget to clean the area of the caliper where the pads sit ( lube with a smear of copper grease) Not to much as this will contaminate the pads.
when finished the pads just check the flexable brake hose for position (clearance from the road spring) .These have been knowen to rub on the spring and fail.

Low pad wear won't put the ABS light on.It has to be a fault with the ABS system it's self,usually a wheel speed sensor fault.Does the ABS still work??.
Re-rear pads,the rear calipers have a tendency to seize,this can lead to high pad wear and longer handbrake travel.Check the wheel spins freely when jacked up.If in any doubt,get the brakes looked at proffesionally.Please don't take any chances with your braking system.Sorry if this sounds condecending,but I have seen too many DIY brake jobs that are positively life threatening,i.e new pads put in the wrong way round,the metal backing grinding against the discs instead of the friction material.The customer swore blind he hadn't touched them!!!
P.S,if you are going to replace the pads,don't use copper grease on the backs of them.There is special white grease specifically for this job.

I'd rather push my Alfa than drive a BMW....

Check the Laguna 11 section, wheels and tyres, for handbrake faults!

Thanx guys,, i'll book it into renault for service soon, about 5k and get them to check it out then.

The brakes are working fine, ABS is spot on , had to use it the other day when a dog ran onto the road from between parked cars,,,

if it's a sensor, could it just be a reset or will the sendor actually be faulty ? if so, are they expensive to replace ?
