Caliper bracket bolts

[Funkyboy]

Hi all,

Before I change my front discs on my 14plate E250 can anyone inform me how difficult is it to remove the caliper holder bracket as I will be using a trolley jack and axle stands so won't have that much leverage.
Thanks

They will be tight so maximise access by turning the steering to give you the best angle on the bolts

Use a new spanner or socket to remove the bolts .I had problems with one of mine so i used a small bottle jack under the ring spanner screwed it up to break the bolt open . I did everything possible till i came up with this idea . I recon you wont have any problems if you use the right spanner .

I've got a bottle jack so will try this if I have any issues.

Breaker bar and a good quality socket will be plenty.

They are tight and will need a well fitting socket and breaker bar. Turn the wheel to full lock if necessary to get the best access to the bolts I had no problem doing mine on a trolley jack but obviously if the bolts are going to need some serious grunt you take precautions to limit how far the car could fall. I never rely on a jack alone to keep me safe.

Preferaby use a single hex socket, rather than risk taking rounding the bolts wit a double hex.

If the head if the bolt is shallow, another thing I've done is to grind or turn the face of the socket to remove the lead in taper. That ensures the socket gets maximum purchase on the bolt.

Frank i could not budge mine ,and like you i was on my drive with no room to use long tube or breaker bars . The trusty jack did the job with ease . Good luck

If no heat available boil a kettle and pour over the bolt heads, helps release thread lock!

D2028 Yes thats another good idea . I modified an old electric soldering iron . I get it red hot place it on the bolt head for few mins it works wonders on stuck bolts and nuts . Also a penetrating fluid in spray tin - Rostoff Ice made by Worth .

It’s a nine year old Mercedes, I don’t think the caliper/bracket bolts are likely to be too difficult to remove? You’d have to be pretty unlucky to have to use heat etc.

Main issue is where people who don’t know what they’re doing and/or with pound shop tools slip off/round off bolts etc But generally the caliper bolts are pretty heavy duty and the threads usually have a locking compound on them which helps keep corrosion and dirt out

Decent breaker bar and socket first, save the kettle for the cup of tea afterwards

Will Some new cars have had work done , and the shop never used torque settings , just a fully wound up rattle gun And i was talking about cars older, like my own 33 years old car .Because some bolts have never ever been removed. As for breaker bar, if your stuck on the drive with no room a breaker bar would be of no use..

I used a Makita impact wrench on the Caliper bolts in the end. Should have reached for it straight away

Your lucky to be able to get in there with a reattle gun to open them up

I really don’t get the issue with access, you just turn the wheels as mentioned then jack the car up and ideally put it on an axle stand.

This is one of those threads where the job could have been done quicker than the time it takes to type out the message
